Repairing Interior Plastics

[kennythewelder]

Worked on my dash some more today. I got all the cracks reinforced. Got some of the cracks filled in with JB Weld. As I said before, it is a process. I will need to fill in with JB Weld some more and sand smooth. Then paint with some fabric and vinal paint, med gray. As you can see I cut a hole in the dash where one of the cracks was. Then cut some aluminum as a backer, and back buttered it with JB Weld. Then I JB Welded that and reinstalled most of the plastic. I will keep the clamp on it till tomorrow evening.

Alternatively I was considering gluing a metal backer to the inside of the dash to level/stabilize the two sides, then filling with JB Weld Plastic Repair Putty and very carefully painting the puttied gap.
