This is supposed to be flexible so I hope resisting to cracking.

Seems simple enough, with a 50-50 mix and long curing time.

To test the adhesion to the relay board plastic, I partly filled two cavities.

Me too! It might take 48 hours to fully cure.

That's the stuff I used and it works great. Definitely the way to go. I had planned to sell off my left over (there is enough for 3 boards in a pack) but kept finding uses for it in other projects and decided it was worth keeping on hand.

Visited the body shop today, and progress has begun again. They are hand sanding doors and lids.

First, check on the flexible epoxy from 2 days ago. The bit left in the mixing cup is nicely solid.

And also very flexible, able to fold in half and spring back.

I also checked the test spots I poured on the relay board. The epoxy sticks very well, and I was able to peel up a bit only with quite a bit of force.

Next, I tried some paint stripper on the blacked out trim from my car.

The stripper works well enough, but reveals that like on the chrome bumpers, some PO sanded the polished surfaces before painting.

Then I started a test for materials to protect unpainted steel. I sprayed these on a piece of raw square tubing. These will need 24 hours to dry.

Finally, I gather some miscellaneous small parts with variable amounts or rust, like the retaining clips for the targa hoop trim.
