Ultra-black is made by Permatex, it's a silicone gasket maker. It sets up quickly, withstands
temps of up to 500 degrees, and is very resistant to oil and fluids. Honestly, I don't really know
why anybody would use that orange crap, knowing that this stuff exists. Just keep in mind that if
you're trying to seal up an area that has been leaking oil, you're going to have to get that area very
clean and dry before you can achieve a proper seal. Good luck!
