I am rebuilding the drivetrain on my 58 viking, and I intend to paint all of the components. I was told by a friend to never paint a transmission. Understandable for an auto, they need all the cooling they can get, but I don't feel like the sm420 really needs it. I want to put on a thick (~3 mils) layer of epoxy paint, Would I be fine, or should I install some heat sinks?
