What is used on the plastic model car kits? Why can't that be done on a larger scale for fiberglass bumpers? SNS Chrome is the only place I ever heard of chroming non metallic components, but the last price I got some years ago was close to $400 per bumper.
I think it has too do with the actual type of plastic. Models are made of styrene and fiberglass is a matting reinforced resin.
