Will fiberglass adhere okay to that plastic whatever-it-is material that bumpers are made of? My bumper also has unsightly ass crack and as we all know, crack kills. I was thinking of using some plastic epoxy resin stuff along with something to support it, and basically gluing it from the back, and filling the hairline with bondo or some type of filler before sanding and painting it. I take it this is a bad idea?

Sorry if I'm jacking the thread, I just figure it's still relevant and applicable though

OEM bumpers are made of polyurethane. Fiberglass dosen't stick to polyurethane unless you prime it first. (or unless you've made an isotopic/epoxy/synthetic polyester blend that does stick like me ) (BTW: Matt & shannon, it's still holding!! ) so anyway. if you can pull your "cracks" together, than clean the back (unpainted) side. pull the cracks together and tape the front (painted side) prime the now clean back (unpainted) side. Allow to dry. Turn peice face down; Apply the proper mixture of fiberglas resins (with catalist, duhh) to the primed & dryed side and allow to seep into any of the "crack" that may be left. Coat over with a few small squares of FG cloth and continue to layre the cloth with more resin. allow to fully dry. if done properly then the reverse side should have little to no crack left. any remaining crack can be filled in with one of those ghetto "paint-pens" and then buffed a little bit to fade in unnoticibley.

Note that this is the cheaper way of doing it. If you are a profesional body guy, then you and me both know that this is a band+aid solution, that works pretty well for $8 or less
