My .02
Black RTV: general purpose, good all around, water pumps etc.
Blue: Most oil resistant, best on oil pans, timing covers etc
Red: Hi temp, good for intakes etc.
Copper: very high temp, also somewhat oil resistant: very good all around.
Can be used in place of exhaust gaskets for headers.
I try to keep both the blue and copper on-hand. Between the two, they can
handle any sealing job.
BTW Permatex also makes some stuff in a can. Can't think of the name off
hand. You squirt it out of the can just like cheese in a can. It's usful
if you are doing an entire engine rebuild. There is just enough in the can
to do a whole engine. (At least a SBF). It's not cheap at $11 per can,
but it is easy to work with. It is firmer than regular RTV. Squirt it out,
let it sit for a minute or two and then you can actually move it around
without smearing it.
Later.
