ok i do custom bodywork at a body shop and all i can tell you is this fibeglass you can do anything to .......urethane on the other hand you are limited even molding it in is very expensive cause the epoxy for it is expensive.when it comes to paint and how it looks fiberglass looks like crap not stright but you can prime it with a polyester and once you block it ,it will come out nice urethane on the other hand has a agent in it that dosent like paint so you have to soke it in a solvent cleaner then put this plastic prep and then you have to put it in a flex agent if you do all that it will trun out great but good luck with what road you go down thanks
