If there is nothing wrong with the paint I wouldn't recommend stripping it. If so just scuff it and feather out all the chips and scratches with 320, then prime and paint. If the paint is checking, flaking, or just really bad you'll want to strip it. They make special paint strippers for bumpers or you could have it walnut blasted. If it is this bad you might want to locate a bumper refurbishing place. They have some around here that boils the cover and fixes any damage. When you get the bumper back its pre-primed and looks perfect. They are actually easier to repaint than the factory replacement bumpers nowadays.
ya the bumper doesnt have any damage, my previous one did thats y i got it. But it has some paint that is flaking so i think i should sand it down or find the special paint stripper. I would like to send it to a bumper referbishing place but im 16 with a part time job trying to get it insured as well as in nice condition. Insurance Companies are a big pain in the ass, i cant believe they want $4000 a year. and then some insurance companies tell me that the toyota supra is a restricted car, they dont insure it>
thnkx alot for the posts it is really helpful specially for a 16year old with not that much experience.
I just finished primerin' my whole car, wat a job. shoulda took me longer but it already looks better hehe.
One piece of advice from our resident PPG paint expert Jamie Bergen (aka Ghostrider).
When mixing the paint & shooting it, you'll also want to make sure that you have added a flex agent to it.. This way when the bumper gets "bumped or squished", the paint will flex w/ the bending of the bumper itself. W/O the flex agent, the first time the bumper gets bumped or squished, the hardened paint will crack & possible come right off. You want to make sure that the paint has some give in it.
Hopefully Jamie will chime in soon, she has worked for PPG in the past I believe???
What kind of primer you use is really dependent on what paint you use, i.e. Dupont will have a recommend Dupont sealer and this Dupont primer for this Dupont paint. You definetly want to use flex add in the paint to prevent flaking. This is probably what happened to the bumper you have. If I were you I'd find a auto paint store locally and I'd go in and talk to them about what you are going to do. They should pretty much be able to tell you what you need to do and buy. Most of these guys are pretty knowledgeable about what they sell.
