I previously used it on the oil pan on my 383 in my Super Bee... You have to use 2 layers due to the windage tray of course.

Taking it off was not fun... it took a long long time to take it off... like a couple of hours with the engine on a stand and using a razor blade and a pry bar.

It sealed great, but I wont do it again. I damn near had to wreck the pan taking it off.
