With out starting a war, I have done this for 41 yrs. with Rustoleum 7769. It seals
the internal surfaces and the only thing that takes it off is Nitro or a hot tank. Ford
used a coating in the 8" & 9" rear ends, Caterpillar and I believe John Deere use a
coating inside the engines & gearboxes. If anything it will raise the temp by sealing
the surface just like the outside of the block. It helps keeping the engine clean,
the crap in the pan for draining and it could help sticking the dist. in the Model A.
I doubt anybody could tell if an engine is painted on the inside by the water temp,
oil temp, or when you drain the oil.
