i got a urethane xenon bumper up front and fiberglass buddy club in the rear. man fiber glass just sucks ass, but thats the reason i got it for the rear only, cuz the rear doesnt hang very low but the front does. when i was mounting the rear the sh*t started cracking and was a pain in the ass to fit right. about urethane being harder to paint, its acutually easier, thats what the guy that does my body work saidm cuz fiber glass has lots of holes/bubbles/blemishes and what not that have to be sanded out b4 it can be prepped for primer and paint.. and w/ urethane it just needs to be sanded down w/ a thin grit sand paper and a flex agent has to be mixed to the paint.
