Please Help

[wilo]

right had my first mishap i was painting the chassis of the F40 Monte Shell yellow after i primed in Grey, i followed what i thought was the right path to dust coat a few times then wet coat but no matter what i did i could not cover the grey, so just tryed a thicker coat of yellow ( i am using TS spray paint) but totally screwed this up runs everywhere so i tred to wipe them down DOH and have just ruined it. first how would i go about stripping the paint of the chassis and when i have what is the best way of painting it? should i use white primer?
PLEASE HELP ME

Sorry to hear that wilo. I believe you should use white primer for a light colour like yellow. So for now, strip it with oven cleaner and start again.

What I usually do is I primed the body with grey primer and then I used white primer on top.

Remember when you use easy off oven cleaner, the fumes are what does the job. You should spray the oven cleaner all over the model and put the model in a box. By doing that, you trap all the fumes inside the box. Leave the model in the box for 1-2 hours, strip. Bear in mind that you may have to do this 3-4 times to strip all the paint if you've used TS paint.

To strip the paint get a container and fill it with enough brake fluid to submerge the body. That will take care of the paint. Yes, white primer would be a better option than the grey, or you could follow grey primer with a solid coat of white, and then the yellow. Yellow is somewhat translucent, and is very dependent on the base that it is being sprayed over. Hope this helps

The best way to strip it is to go down to your local chemist and get a bottle of 99% isopropyl alcohol. Pour the whole thing into a coverable container that the body will fit in, and leave it to soak for a few hours. Any residual paint can then be scrubbed off with an old toothbrush. the primer will likely come up also.

Light colors (white, yellow, red, etc) don't cover real well- so they're going to look much better applied over white primer than grey. Building up in light coats is a good technique (runs are to be avoided at all cost- they're very hard to deal with afterwards). But you're not likely to completely cover a grey primer with a yellow spray no matter how many coats you use.

No worries- just strip it, clean it up, and try it again.

Either dunk it in a container of brake fluid or CSC, one will do the trick.

I strongly agree, use white primer. Yellow is a BITCH to get on right, and the worst thing you can do is lay it on too thick. Stick with Tamiya primer as well, in this case. Just my two cents.

When you have stripped the body nip down to your local Halford's as you are in the UK and you can get yellow primer.I have used this on many yellow models before.Spray with grey to check for flaws first than when you are happy with the finish dust a small amount of the yellow over the grey.It seems to just take the edge off the grey and your yellow top coat should cover a lot better.

cheers all i am tying the oven cleaner trick at the moment because the wife had some in the house so it was easy to have a go of, MPWR will i be able to get 99% isopropyl alcohol in the UK? (if so is it called the same here?)
Stevenoble do i need to get a plastic primer or will any yellow primer do the trick?
cheers you have all been a BIG help as usual.

You might struggle, I called to a few chemists and they wont sell it to the public over the counter. I managed to get some via a friend but find brake fluid to be more effective with automotive paint like that from Halfords.

I’ve managed to get 90% alcohol form the local chemist where I am. He had some on the back, and sold me some. Anyhow Wilo, you need to use white primer, but as Steve says, halfords have yellow primer. My completed Pennzoil in the motor sports completed section was sprayed with yellow primer from Halfords, worked a treat. Use the yellow primer over grey plastic primer. Should be fine.. Tamiya plastic can take a lot, but use plastic primer as a protection first.

Hope you get it stripped and all sorted, I’ve had a few mishaps myself, we’ve all done it. I just hope you don’t fly off the handle like I tend to. I’ve got a reputation of “going off on one” when things go wrong.. LOL

....if so, then it's available from Maplins, either 400ml aerosol or 1l tin.

well mickbench i did punch my door in rage :-( i am a bit up tight when i come to messing things up . and was tempted just to bin it and start the Ducati but the wife persuaded me to carry on with it :-)

[mickbench]

Wilo,

Is that the same ducati that I’m currently working on? I’ve been working solid on it now for two weeks, and I’ve still got weeks of work left. LOL. The F40 your building is in my stash, I’ll get around to it one day. Hang in there; once you get a few models completed, you start to feel a little better.

Anyhow, yellow is perhaps one of the hardest paints ever to spray, I’ve had some fun trying to lay yellow down. It’s tricky, but you learn from your mistakes. Therefore, as I make a lot of mistakes, I’ve learnt a lot.

[MPWR]

Maybe instead of the Ducati next, we can find a curbside kit to do first. Niehter the F40 or the Ducati would have been kits I would recommend for a first or second go. I admire your ambition, but there are some easier ways for you to pick up these skills!

Most of us have had moments of furious rage when some step of building has just completely failed. Totally OK. But the best thing to do is just walk away for a while. My F50 sat out for about 5 months while i trembled in rage about the rear PE screen. But it's amazing how much you can correct when you return to a project with a calm mind.

I wouldn't have guessed isopropyl would be restricted in the UK, but appearently it is. In the US, it's simply rubbing alcohol, used for first aid and the like. You can also buy it in larger cans for fueling alcohol stoves. Funny it should be restricted- it's not nearly so dangerous a substance as say, unleaded petrol.

Yes, there are a number of other things you can use to get paint off. Many of them do work faster than alcohol. But given the choice, I always like to pick the least toxic and safest for plastic option. Isopropyl works well enough for me that I don't need another option, and I don't have to worry about toxic disposal afterwards.

And yes, yellow or white primer will work fine. I've never tried colored primer (can't seem to find it in the US!), and I've heard it works very well. But on the other hand, you can use the white Tamiya under reds and whites, too.

What model would you recommend for my next model MPWR i have just got a Tamiya Mercedes CLK-GTR and a TAMIYA PENNZOIL NISMO GT-R of ebay for next to nothing. Also i just got some brake fluid from halfords how long should i leave the chassis in the brake fliuid? Also i could not get WHITE plastic primer so i got normal WHITE primer and i was just going to prime the chassis with the grey primer i have, then mist the white over this, would this be OK? also the only yellow primer they do is called filler primer is this the one you guys where talking about?

It's much tastier to mix and drink though which is why its a quasi-controlled substance here too. Big alcoholism problem in C&EE countries
You might also try electronics suppliers for the alcohol, I believe it is widely used in making electronic circuits and cleaning parts?
