Yes do I use the same grit for the body as I do for the front?

What you mean is Urethane........this might help in your repair: http://www.vetteweb.com/tech/vemp_0810_c5_urethane_bumper_repair/repair_images.html If you just want to sand the lacquer paint just use 400 or higher. It all depends on what you're trying to do.corvette440hp2009-04-06 15:33:10

Hey thanks I am just getting it ready to paint it.

[QUOTE=ossw1]Hey thanks I am just getting it ready to paint it.[/QUOTE] Just rough it up to get the paint to adhere to it. Make certain to clean the area with denatured alcohol to remove sanding particles, wax etc. You need to add flex agents to the paint for the urethane material.
