One for the epoxy lovers

I'm pretty sure it doesn't. I do a lot of powder coating. I have gotten pretty good at coating badly pitted and damaged metal. I do whatever I can to repair the metal (weld, sand and hammer and dolly), and then use JB Weld like filler. It fills in pits and other flaws, sands smooth like filler and is good up to 500 degrees. It cures so hard you can drill it and tap it with threads.

Some years back, I had Lingenfelter & Hogan sheetmetal intakes here, both finessed with epoxy. Anywhere the epoxy is "feathered in", or at an edge spread thin, pieces will eventually chip or flake off. If the intake or head will get routine inspection/maintenance, it wouldn't pose a problem, it'd be spotted & fixed before pieces started leaving..
