Airfix Porsche 928 S4 1:24 WIP

This is possibly my first exposure to a proper sports car when I were a wee lad because one of my uncles had one in that 'lovely' bronze metallic that was all the rage back in the day.
I also had a big radio control 928 that I never had batteries for but loved all the same.

So here it is after a long time looking for it in 1:24 scale.
For those interested, this is a rebox of the Italeri kit of the same name except that kit had body parts molded all in black. For some reason, in the kit I got, the body was blue and the bumper parts were black.
If I'm correct, this kit was also reboxed in the US by Testors.

They used to come up quite regularly on ebay but these days, they seem to be getting scarcer.


First things first.
Attached front and rear bumpers to help fix a break at the rear and to check for alignment with chassis.

Body proportions look good and top down, you can see the coke bottle/narrow waist thing that they have going on.

You can also see the break in the rear here. Fixing on the bumper helps give the whole area strength.

Had to fix a badly cut part of the windscreen frame.
All I did was slowly add surface primer to fill the cut area and then when it was not quite fullt set/cured, took a sharp blade and carefully trimmed it to match. A little sanding later tidied it up.

https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZs534PMZmI/AAAAAAAAAQA/AEEn0WXRtN0/porsche%20928%20S4%20009.JPG

Also had a couple of sink marks to fill in.
You can also just about see where I filled in some of the panel gap because it was a bit too wide here and uneven.
https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZs5yvgpu2I/AAAAAAAAAPk/_AbLtxHR2C4/porsche%20928%20S4%20011.JPG

Same on the other side with panel gap.

First coat of primer.

After a good sanding all over with 2000 grit, I brushed the surface with a hog hair paint brush that's nice and stiff so it gets all of the sanding dust out of the panel gaps. Then when it's dry I gave it a decent coat of warmed primer.
Primer is Halfords Automotive Primer.

https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZs6bVmqz6I/AAAAAAAAARI/RCxgEu8WpuA/porsche%20928%20S4%20013.JPG

Gap here still not quite right.
https://lh6.googleusercontent.com/_CiFVeDwpZmA/TZs6cL6q-OI/AAAAAAAAARM/DSBLO47MInk/porsche%20928%20S4%20015.JPG

Gap here is much better.
https://lh4.googleusercontent.com/_CiFVeDwpZmA/TZs6d0HJ_TI/AAAAAAAAARQ/BrDd3DoOPUo/porsche%20928%20S4%20016.JPG

Still need to fix that join line, tidy up sink holes and that boot hatch shut line too.
https://lh4.googleusercontent.com/_CiFVeDwpZmA/TZs6d4BVGxI/AAAAAAAAARU/kw8G_SdKiOc/porsche%20928%20S4%20017.JPG

Looks rough here but the fix on the window trim here hasn't been sanded yet.
https://lh6.googleusercontent.com/_CiFVeDwpZmA/TZs6eSlZqXI/AAAAAAAAARY/kdjjsNDV40I/porsche%20928%20S4%20018.JPG

Other things done.
I (over) scribed the panel gap at the lower part of the front bumper.
On the kit, this was where you had to glue so the panel line was gone altogether. I noticed afterwards in photos that the real gap in very, very fine.
https://lh5.googleusercontent.com/_CiFVeDwpZmA/TZs6gFVdF5I/AAAAAAAAARc/P8wdzLhpX9o/porsche%20928%20S4%20019.JPG

I also over did the same gap at the rear bumper.
Apart from that, panel gaps are all very prominent, very even, very Porsche.

https://lh4.googleusercontent.com/_CiFVeDwpZmA/TZs6gv5Gz6I/AAAAAAAAARk/F6VpJjDhDIY/porsche%20928%20S4%20021.JPG

While I was at it, I also prepped and primered some other parts.
https://lh5.googleusercontent.com/_CiFVeDwpZmA/TZs6bEUBH_I/AAAAAAAAARA/PuessEkNfXA/porsche%20928%20S4%20022.JPG

More prep.

Usually, my first coat of primer almost gets sanded all away as it's used purely as a surface filler for all of the fine scratches you get from the sanding of the bare body. With this one though, probably because of the simple surfaces, after a generally all over with 2000 grit again, I noticed there wasn't much texture in the primer and it was pretty much as flat as normally like so a lot of primer was still left.

https://lh4.googleusercontent.com/_CiFVeDwpZmA/TZs69MqgvMI/AAAAAAAAASU/oAyRl821_lc/porsche%20928%20S4%20023.JPG

Fixed windscreen trim.
https://lh5.googleusercontent.com/_CiFVeDwpZmA/TZs69XNsh4I/AAAAAAAAASY/QRR0m_TGEdE/porsche%20928%20S4%20024.JPG

So, I was happy enough with it to put on some proper primer.
Tamiya White Fine Surface Primer.

At this point, I had removed the bonnet as per instructions.
https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZs6-aF2ANI/AAAAAAAAASc/bf4apZP691E/porsche%20928%20S4%20026.JPG

And after a little sanding with 2000 grit again, I took some micromesh to it to get it really flat and smooth and shiney.
https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZs6_USu1SI/AAAAAAAAASg/uX-OYJwe_hM/porsche%20928%20S4%20027.JPG

Because I mention it all of the time about shiney primer, I turned off all of the lights to capture a reflection in it.
https://lh6.googleusercontent.com/_CiFVeDwpZmA/TZs6_Q6dhHI/AAAAAAAAASk/C05U6Bwv_iI/porsche%20928%20S4%20028.JPG

And a closer shot.
https://lh5.googleusercontent.com/_CiFVeDwpZmA/TZs68uqLG4I/AAAAAAAAASQ/0Do9280jZgE/porsche%20928%20S4%20029.JPG

You can at this point, still see some distortion in that reflection and that the lines of the reflected image aren't that sharp. This means that it could do with at least one more seeing to with the micromesh before applying colour.

And that's it so far.
Colour has yet to be decided as I'm torn between some funky and 70s/80s or good old reliable black.

Great start. The Testors 928/s kits i have have opening doors, but i don't know their mfg.

I'm really glad someone has taken the time to do a WIP for a paint job. This is my biggest down fall on the the models i make in getting a sweet finish and i thikn i understand a little more now where i may be going wrong.

I've just been building an evo 5 and had pre sanded car before applying tamiya white primer. Applied that but didnt sand it down. I then laid down a coat or two of semi gloss black, sanded that back smooth and noticed where the washer wipes were i was going down to the base plastic ( even using 12000 grit ). Anyhow to cut a long story short my paint job isnt looking as good as this prospectively is so i'm appreciating the tutorial.

Thanks

Good job with the small corrections you brought to the body :bigthumb:

I'll follow this carfeull 'cos I'm sure it's going to be perfect once finished.

I would like to follow this closely also as a learning curve too but, it seems that I cannot see the photos... Could anyone suggest what I should do and if this is only on my computer?

...it seems that I cannot see the photos...

is anyone else not seeing them?


Last 2 of the body in primer.
I went over the body again where I still saw some texture with 4000 micromesh, taking care not to go over the edges of the bodywork.
If at this stage I got down to grey primer, it would mean going over it with white primer again and with each extra layer of primer (and paint for that matter), you will risk getting more texture onto the surface.
Just a couple of close up shots of the kind of reflection I get on my Primer before I apply any colour coat.
They're a little blurry because I couldn't get my camera to focus properly on the reflected image so I left camera at a fixed focus setting and moved until it looked sharp to me.

Interior was kept a simple black on black.

I broke up the monotony by applying some texture to the transmission tunnel, floor and rear parcel shelf with some Plastikote Suede Touch paint before spraying on Halfords Automotive Satin Black paint. In hindsight, Black on black was probably not a good idea as I think I will just paint the body Tamiya's lovely TS14 Black. Should Probably have painted the "carpet" sections flat black too.

Here you can see the very fine texture the Suede Touch paint gives the surface.
https://lh5.googleusercontent.com/_CiFVeDwpZmA/TZxq11mNPHI/AAAAAAAAATI/q3jlynNuqyQ/porsche%20928%20S4%20034.JPG

I reckon this would do nicely for getting the sand-cast texture on certain red cam covers and intakes...

While the primer was curing or drying after sanding and washing, I made a start on the other bits.

Rear suspension nicely done; a little fiddly to align together to fit on model chassis but pretty good looking.

https://lh4.googleusercontent.com/_CiFVeDwpZmA/TZxq3_e4skI/AAAAAAAAATU/zPjX22WfMOs/porsche%20928%20S4%20036.JPG

And some other bits.
https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZxqzwRrrtI/AAAAAAAAAS4/uUyJGOGlH0s/porsche%20928%20S4%20037.JPG

Engine wires are normally black on Porsches but this looks like it will be a very black car so I figured a little red in the engine bay would be a nice touch.
Hoses to radiator are bits of bent 4mm and 2mm styrene rod. Will add some BMF hose clamps later.

is anyone else not seeing them?

Everything's alright for me.

Here's where I may horrify some people.
First of all, let me say that I am a lazy painter. Every time I add another layer of paint or primer, I notice more textures appearing which is why I spend so much time and effort making my base primer as perfect as possible; so I can avoid spraying too many coats of primer and/or paint.
If you look back, so far I have only put on one layer of grey primer, sanded then one layer of white primer which I have sanded "perfect".
The idea being that the less texture in my primer, the less texture in my paint.
Now comes the horrifying bit.

I don't do mist coats.
I start by doing one even, light(ish) wet coat over my finished primer and this is what it looks like.

https://lh6.googleusercontent.com/_CiFVeDwpZmA/TZykJ-iGVFI/AAAAAAAAATg/yCJtG9F5SeE/porsche%20928%20S4%20038.JPG

https://lh5.googleusercontent.com/_CiFVeDwpZmA/TZykKRN_9UI/AAAAAAAAATo/S2x0yjYXbqM/porsche%20928%20S4%20039.JPG

https://lh6.googleusercontent.com/_CiFVeDwpZmA/TZykKeNEt3I/AAAAAAAAATk/2cm-8enH9xM/porsche%20928%20S4%20040.JPG

There are a couple of spots of dust, one fisheye and one spot that might have gotten too much paint.
This doesn't matter to me as this layer of paint, like my layer of primer underneath it, I am willing to sand away as much as necessary to get it smooth and perfect. I tried misting over vulnerable areas for a while but that never worked for me, mainly as I don't have an airbrush and with a can, I never found it easy to get a consistant and meaningful mist coat.
This single layer of paint I tend to leave for at least two days in a warm place before I touch it.
After it has been checked, sanded and checked again, IF it needs another layer of paint (i.e some primer is showing through) then I will add another wet coat on top.
So in summary, my method is
one layer grey primer
one layer white primer
one layer paint.

Of course that is the perfect painting scenario for me.
Extra coats of paint are done when necessary, not as part of the course.
If I need to add an extra coat of paint, I will work the existing coat of paint more to avoid getting too thick a coat of paint on it. In short, I sort of treat the first layer of paint like primer when I need to add more paint.

Gave the paint a quick once over with 2000 grit
https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZ8w44AYZdI/AAAAAAAAAVM/GE81jTBvCmY/porsche%20928%20S4%20041.JPG

Then went over it with 4000 micromesh.
For reference:
left = after 2000 right = after 4000
https://lh6.googleusercontent.com/_CiFVeDwpZmA/TZ8w5IBao-I/AAAAAAAAAVQ/EtaPFy2mAYY/porsche%20928%20S4%20042.JPG

And now there's a couple of spots that need to be fixed before one more coat of paint.

Fisheye that's left a pin hole.
https://lh3.googleusercontent.com/_CiFVeDwpZmA/TZ8w3lSpr8I/AAAAAAAAAVI/E2HgmkSoVMk/porsche%20928%20S4%20044.JPG
I will spray out some paint so I can dab/fill in the hole with a needle.
When cured, that will need to be sanded.

Where there was a little overspray.
https://lh4.googleusercontent.com/_CiFVeDwpZmA/TZ8w5bVXwgI/AAAAAAAAAVU/njHfkiP2X0U/porsche%20928%20S4%20043.JPG

Took a small chip out here whilst sanding the over-spray so this will also need to be filled with needle on paint as before.

Very nice so far! :) Love it.

No problem seeing the pics here.

Cool, funky kit of a cool funky car. Fun to see a 928 here.

Paint looks great- but why spray white primer over grey, and then black paint? I'm thinking that the white layer isn't doing anything for you. :confused:

i wondered too. I found tamiya white primer pants.

Not that I'm any expert here but I thought the exact same thing. Nice paint job anywho :)

I'm following this with great interest, especially since this is the first thread I've seen of this kit. Really looking forward to seeing your progress!

Simple really, I only had Tamiya Fine Surface Primer in white when I was prepping the body.

i wondered too. I found tamiya white primer pants.

How do you mean?
Tamiya Primer's are by far the best primers I have used out of a can. Nothing else comes close to laying down a flat surface that's easy to work smooth.


A couple of new pics.

The exhaust.

A little trick of mine.
I have a jar of Tamiya Flat Aluminium (XF-16) that I've added Tamiya Acrylic Thinner and a water to.
What this does, is make the paint go bad and seperate. After a while, all of the paint particles clump together at the bottom of the jar and you get a layer of the solvent on top. The reason I do this is so that now, I can paint using the clumpy part which leaves a nice grainy texture when it's dry.

https://lh6.googleusercontent.com/_CiFVeDwpZmA/Ta3HoF3ouuI/AAAAAAAAAVk/9KMeyAsUo7Y/porsche%20928%20S4%20046.JPG

You can see it a little better here
https://lh3.googleusercontent.com/_CiFVeDwpZmA/Ta3LapXrUZI/AAAAAAAAAV4/dmjZt2qNvwY/porsche%20928%20S4%20049.JPG

After that, I mix a little Citadel Skaven Brown Ink with Citadel Mithril Silver to get a rusty steel kinda of colour and use this to wash over the textured Tamiya Flat Aluminium.
This smooths down some of the grainy texture and takes off some of the shine that XF-16 has and you end up with this.

https://lh4.googleusercontent.com/_CiFVeDwpZmA/Ta3LUPkOHlI/AAAAAAAAAV0/N_DkFut5WK4/porsche%20928%20S4%20050.JPG

Drivetrain:
The molded on belts have been removed from the parts leaving just the pullies and the belts are replaced with Tamiya Masking Tape cut to size and painted Flat Black.

https://lh4.googleusercontent.com/_CiFVeDwpZmA/Ta3HoqewMWI/AAAAAAAAAVs/ri4OMTcjVns/porsche%20928%20S4%20045.JPG

Normally, I replace the shocks and springs with some styrene tube+rod scratch built items with coiled wire but I wanted a quick build so I just painted them here.
First I sprayed everything Automotive Satin Black.
Then I carefully painted over the top edge of the molded on spring/coil with Citadel Skull White which I find is better for this than Tamiya's Acrylics (Flat or Gloss) followed by Tamiya Gloss Red (X-7).

Here, the belts have been done and I made a start on what I think is part of the throttle controls that are attached to the side of the intake plenum.
It's just little bits of 0.5mm styrene sheet drilled then cut (it won't work the other around) and painted Citadel Mithril Silver.
https://lh5.googleusercontent.com/_CiFVeDwpZmA/Ta3Hoq1V_2I/AAAAAAAAAVo/noPKFVz8pWQ/porsche%20928%20S4%20048.JPG


And that's it so far.
There were a couple of spots on the body that went through to Primer so my hopes for a two coat finish died rather quickly. I may just mask off and spray those two panels and if I do, I'll make a point of taking photos of that.

tip for the exhaust painting is terrible !! :thumbsup:
Probably the best way yo make parts get a 20 years old look in one brush shot !!

How do you mean?
Tamiya Primer's are by far the best primers I have used out of a can. Nothing else comes close to laying down a flat surface that's easy to work smooth
.

I think my mistake was not laying down a grey coat first hand when spraying a red plastic shell, found it hard to get the red out of the equation.

Loving the exhaust - looks fantastic.

That's not a fault of the primer but a problem that occurs with red plastic mouldings.
It's not something that happens with all red plastic but it is quite common although I can't say I've noticed it except on one build of mine where it made the planned deep metallic blue a lovely deep metallic royal blue instead
(it's the blue corvette in my sig... click to get to my profile where they're all listed)

There's a sealing primer that people recommend for preventing it but I've never tried it.

small update on engine parts.

almost wired all of the bits on the intake plenum.
there should be one more cable that goes to the throttle part but you don't miss it because it's tucked away behind the others.
The screw cap should also be in yellow but I'm still looking for a good opaque and bright one.

Looking good, great progress.

Great thread on a great car ;)

A few tips on the engine colors: The oil filler cap was originally Yellow on the S4's and the seam on the middle of the air filter housing is usually orange (the orange rubber seal of the actual filter is squeezed between the upper and lower air filter housing).

The intake plenum and valve covers where light beige rather than silver but often look more like silver in pics, and the paint on the intake tend to flake off so many have repainted them with silver engine color.

Found a reference picture:
http://images.gtcarlot.com/pictures/37379297.jpg
The fuel pressure gauge on the front of the passenger side fuel rail is not stock, otherwise it looks pretty original.

I stopped modelling 1/24 some years ago and been busy with 1/32 scale slotcars instead, but the 1/24 "urge" is starting to itch again, so thanks for the inspiration to dig out my half finished Testors, Fujimi and Gunze 928 kits :)

how are the wheels on this kit?

Right, after a bit of a hiatus, I am back and finishing up kits so let's begin with this one.

After my polishing, I had rubbed through a spot on one of the door panels so masking it is a bit of a re-spray.
https://lh5.googleusercontent.com/-UawR_5rk9Vg/URznXMfMy-I/AAAAAAAABSs/J5PwK8rTExw/s900/porsche%2520928%2520S4%2520062.JPG

After that and a bit of waxing body is done with the exception of mirrors, lights and wipers.

As nice and shiney as it is, you can see by the reflection that the plastic isn't perfectly flat. Much of that is to do with the type of plastic used on this older kit. It has since been re-issued but I haven't yet had a look to see if the new re-cast uses a stronger plastic or not. I tried to best flatten the engine lid/bonnet/hood but well, the reflections are still warped so the part is still warped.

Engine parts have been mated to chassis which is a little bit of a shame because the running chassis without passenger compartment did look quick cool.

Airbox has been re-modelled slightly since last seen and I've added the securing straps as well as the very bright orange gasket to give the engine bay a little more colour.

Just a few things to do then it's off to the gallery for this one.
