I'd like to touch up a black Fiesta XR2i front bumper and body kit which I've just bought. It's looking kind of dull and it seems like the lacquer has worn off in places. Additionally the bumper might need a few dabs of black paint in a patch where the original red paint is showing underneath.
my question is, what's the best sequence to carry this out in? I don't really want/need to strip it right down to bare plastic. If I just rub down the paintwork very gently with some 1200 grit wet&dry to score the surface, will the new black spray adhere to it OK? I'm just going to give it a once over with a Halfords black spray can. Basically I want to know if I need to give it a coat of primer first or whether spraying over the cleaned up paintwork is enough?
After that I'm going to give it a few coats of lacquer. for this, should I let the new paint dry thoroughly and then sand it before lacquering, or wait until it's just touch-dry and give it a light dusting with lacquer?
Cheers!
