i have an 80 camaro, and im restoring it partially, now my rear bumper is the shits and its that poly-urethene whatever stuff :P heheh i dunno, anyways... i wanna know how to scrape/sand/grind it down so i can paint it? any suggestions? and oh yeah does it work the same for the front clip too?

I personally would not use anything coarser than 320 grit sandpaper on a DA to strip the polyurethane bumpers. I'm sure they make a plastic safe chemical paint stripper if you'd like to take that route as well. Just make SURE you get one safe for plastics.

Go with 320 on a DA. Anything coarser than that will damage the surface. I just repainted the 93 Z. That's what I used on the front and rear bumpers and the front plastic fenders. No problems at all. The car is now slick. As you can see when you click on my sig.

Be carefull not to apply to much pressure and/or stay in the same place too long. You will end up with a wavy look from the honeycomb piece under it.

You know your dragging your feet repainting your car when you go to get more supplies and they tell you they don't make that stuff anymore!
