I lucked out and a buddy of mine is giving me the rear bumper off his 75, because hes changing styles. Its not orginal its a flex-fit, with about 3 layers of crap paint on it. Any tips to preping this never worked with these flex-fit bumpers

They are just gelcoated fiberglass. I'd use stripper on it and wash it off good, followed by some acetone. Don't try to flex it too much or you will crack the gelcoat.

A fiberglass safe paint stripper will strip down to the gel coat. Then you can fit the bumper to your body before you prime and paint. Depending on how old it is, it may not be that flexible anymore, so I would treat the fittment as if it were a standard fiberglass bumper and don't over flex it.

The bumper is Urethane, right? I didn't think you could use fiberglass stripper on Urethane?

He said it was not original, he said it is a Flex Fit.
