Probably going to repaint the 78 T/A in the future. The nose piece has developed small cracks in various places. Dont believe all the way thru, just surface cracks. What to use to fill them? The rear bumper has 1 small "chip" in it, someone backed into it. That would need a deeper repair than the "cracks". It should be a flexible repair product from what i've read so far. Some other sites have way too many suggestions from fiberglass resin ( non flexible) to plastic body filler. Any help would be appreciated. thanks
