Is this just a marketing pitch or is this true? http://www.aftermarketkits.com/shop/
They claim, "...that Poly urethane is not what you want. For a body kit you want high quality fiberglass or ABS plastic. Stock body panels are ABS plastic not Poly Euro thane. Poly Euro thane is very hard to paint and will flake after a while."
BTW: Is baby blue the strongest kind of fiberglass?
