Question urethan bumper paint removal

what is the best and fastest way to remove paint from the front and rear bumper covers of 2gen t/a's? do you have to sand all the way down to the unrethane? what is used to fill i gouges and imperfections that primer will not cover?

My body man scuffs the paint with course paper and fills the gouges and cuts with JB Weld then primes.

Sand it down, dont use a chem stripper. The chem strip can soak into the urethane and cause problems later. You can use a small orbit da for the larger areas, but youre pretty much stuck with doing the corners and edges by hand. Slow process, for sure.

Its usually best to sand all the way down to the urethane. That way you remove any of the old lacquer product that could make its way back to the surface and cause cracking down the road. As for fixing the cracks, 3M makes a good product made just for this.

Never heard of using JB Weld for this before. Does it have enough flex in it?

I would not sand or strip with chemical stripper,both will warp the urethane,Id suggest buying new if you can.

I also sand blasted the one on the 70 Judge. I lowered the pressure down to where it was just taking the paint off... it took a while but turned out great and left the factory black sealer on the bumper.

Kent and Fusor both make bumper repair material that comes in a tube form you can get at body shop supply store.It is sandable and I have seen it used to fill in scratches and gouges.

JB weld has its purposes, and this isnt one of them. Although it might be ok for a while in a area that may not flex. the #M urathane crack sealer is best, and flexes, and adhears well.
