Help a newbie - priming

[D.J.]

First: yes ive read the faq, but i still have problems. Ive sprayed a couple of layers but i can already see it will be (is) orange peely If i spray at a great distance it makes peel and if i go closer too much primer gets on. Now its drying, here´s a pic. What should i do?

You just have to get some practice and have it at the right distance. You should strip it down and redo it.

Damn, easy to say, very hard to do (re-do that is).

keep on spraying a few more light coats, as long as you cant see the base plastic you should be ok. then get some fine (about 1200-1500 grit) wet and dry paper- the dark grey stuff, and sand out all of the orange peel using plenty of water. Dont worry if you rub though to the plastic, just touch it up with the spray and carefully rub it down again. Its usually worth waiting a week for the primer to harden up before you sand it, as then theres less chance of rubbing through it. Dont worry- most primers go a bit orange peely. Well mine do anyway, but you can still get excellent finishes.
Good luck, matt.

OK, thanx ill try that. Ive done second time and its a little better - except i rubbed parts of plastic that i shouldnt
Now ill wait a week and then sand away the orange peel.

Ya wet sanding is an option

in future to prevent this, may I suggest you to spray closer, but faster
so less primer gets on but the distance is close enough not to have orange peels

at least thats how I do it =)

Any tips for how to paint? Same as primer?

[Tea]

warm and shake can well beforehand.
give it a hard spray on somewhere unimportant after shaking
never start or stop on the body
start elsewhere and move the can to the body, and stop elsewhere

spray close and fast, in mulitple mist coats, each coat being 10 mins or so apart
last few coats being wet ones.

store somewhere dust-free and allow to dry
after it dries, rub it with 2000 grit to get rid of orange peel and unevenness (that a word ?)

wash and allow to dry
shoot 1 or 2 wet coats

by now the car should be ok

then clearcoating, polishing and waxing is another story.


just my

Do mist coats first which are sprayed at a distance. The wet coat is painted closer and slower so you get a heavy coat on

One more (stupid) question: must i prime all the parts or can i paint the interior without the primer. And what exactly primer does?
Tanx!

Primer " holds " the paint to the plastic. I guess priming the interior is not always neccessary, it is all up to you. But the body is neccessary to me

depends, if you are painting something light over dark-based colored plastic (ie, flat red over black plastic) then primer will help greatly

primer provides a good rough ground for the paint layers to grab on, also it covers the dark base color so you dun have too much difficulty covering it with paint

[primera man]

I only do the bodies to cut down on the cost as primer is getting very expensive to buy.

[D.J.]

One more thing. Did i screw up when i bought this type of paint? Guess ill have trouble cleaning the paintbrush
