I have a question about body fillers for you body shop members out there. Im trying to sort out what filler would be best and least prone to cracking for molding in a body kit. The body shop i am going to recomends a polyester or a normal fiberglass fill but as i was reading up since im overly **** about my car. I came over some other options that crossed my mind.

First filler that is going through my mind is

a metal reinforced filler that is asposed to be stronger and as easy to work with as the standard polyester light weght filler
