that is correct. bondo does not stick to poly and fiberglass is much more rigid . i would only use the ruf or factory porsche aero parts. i actually have some basic working knowledge on fiberglass molding and mold making . i have made some small architectural parts in the past. polyester resin(which most body parts are made from) is nasty stuff only barely good for making a mold in my opinion . it's major problem is shrinkage (because it is cheap). then i would make the part out of epoxy and glass. I am surprised they don't use epoxy in the aftermarket . epoxy resin is much more durable , no shrinkage , resist water better and is not toxic but cost 3 to 4 times more than polyester . I think the problem is that it can not be gel coated but who cares your going to prime and paint anyway.
i have had many thoughts on trying to make parts for the boxster. but designing a part that looks proper and fits seamlessly to the car ("the plug" usually made out of foam or plaster) and making a mold are extremely time consuming for one person.
