what do the difference between the RTV colors?
I am replaceing my oil pan gasket, and I want to use some RTV on the front and back so it wont leak again. All I have is black RTV. but when I took the old gasket off, it had orange RTV on it. Would black work? what is the difference?

black will work fine
in general, black/blue is engine oil resistant, grey is gear oil resistant, orange/red is higher temp, copper is highest temp, not all RTV is made equal though, so read the package for the qualities of the enclosed product
