AM - Slit one of the 2" pieces of tread down the middle with a razor blade and then trimmed the loose pieces of foam. Then I put on two coats of caulk in the freshly cut areas. That should be the end of caulking ... FINALLY.
After putting a few coats of plasti-kote on the treads I realized I should have caulked BEFORE attaching the square treads to the belts. They just look barely acceptable. It's beginning to feel like I need to redo everything on my robot at least one time.
