aftermarket bumper problems?

[MaXenthused]

I'm interested in getting the racing beat front and rear bumpers for my miata. I was wondering if anyone has or knows anyone that has these bumpers installed. I am curious as to how well paint stays on these panels because i've seen tons of fiberglass body kits with paint just peeling off of them. I understand that polyurethane is better but i have yet to find after market bumpers in polyurethane. thanks.
