Father-Son 1974 Duster Project
So here is how I'll fix the sail panels. One of them has a chunk missing where it meets the door so I made a metal patch and JB welded it in place
I'll fill it and apply the texture with a piece of vinyl pressed into wet body glaze putty.
For the cracks I JB welded the edges of the cracks and held the surface perfectly flat and matched with duct foil tape.
Now everyone knows that the JB weld won't cut it on it's own on the damaged edges. So I used 18 gauge by 2-1/2" stainless steel trim nails as gussets or some would say splints. I left one unglued in this pic to show how thin they are, yet they are very strong.
One side had a piece break off so I JB'd it together and added the splints
After this stuff cures, I'm going to lay this fiber tape over the repair and coat it with JB weld. This isn't coming apart.
Once all is dry the foil tape can come off and the face of the repair can be filled with latex if need be.
