fiberglass over bondo?

There really shouldn't be any HUGE problem as long as the bondo is being entirely covered and the fiberglass is able to make a good bondo with the original level of fiberglass(that way there is no risk of it suddenly releasing like crazy, at all). It's just an expensive way to make a mold that you could do fine with like, say, the green florist stuff at walmart. :)1998 Monte Carlo w/

yeah you aren't kidding when you say expensive. I'm on my fourth quart of resin and probably 6th or 7th bag of fiberglass cloth. I bet I've spent over 100 dollars already just on this stuff. I should have bought a gallon container of resin.
