Being that there is no "Stupid Newbie Question" topic I'll just post here in Misc. Currently rebuilding a 1985 Mercruiser 2.5L that was garage stored for years. There was a good bit of internal rust through out, including the cylinders which I had bored out +.030. Soaked everything I could in Evapo-Rust which worked much better than I anticipated. Right now the soaking the head intake and exhaust chambers and already done the manifold.
Now for the newbie question, would coating these internally (not the valves and seats of course) with Eastwood High Temp Internal Exhaust Coating help prevent further rusting? It also seems it will help the engine run a bit cooler.
