I’ve always used Right Stuff but learned it’s just the quick set version of Ultra Black. I’m building a motor with no timeline so I opted for this assuming the longer set time would make for a better bond. It definitely set up harder than the right stuff and I’m happy with the decision, no leaks. Used it for an oil pan in place of a cork gasket.
