Tim Here my 2 cents. Using W40 to spray the engine from the outside after cooling seems OK to me. W40 evaporates pretty fast - so next time you start the thing up , it will not smoke so badly. But waiting for the engine to have cooled down seems impractical to me. But seriously. The danger of corrosion on engines is not on the outside. Inside is what matters. Flying often is the solution. Then I agree to what Dan said about the engine in general. The small continental seem to need an overhaul between 500 and 1000 hours anyway. This is the time when you clean them up and paint them . The costs for an overhaul are relatively low, compared to the costs of changing airframe parts. That's why I spray the airframe from the inside with Corrosion-X every annual, wings included. W40 is not long lasting enough to be good here. Especially all the corners where dissimilar metals are meeting each other, a Corrosion-X (or other similar tested oils) inhibit the intrusion of water or humidity. As for Saltwater Experience : I purchased my brothers Coupe from a guy who kept the plane in Watsonville. I should rather say I liberated the plane. He had it for several years and flew it only for 2 hours in all these years. Of course he acted like an Ercoupe Specialist. It was a soap opera. However, we had to restore the whole plane. Within this year's Center section inspection my brother reported a corrosion free airframe, very much to my surprise. That particular Coupe was not in loving hands for at least 10 years and spent 2 or more years tied down 10 miles away from the pacific ocean. The only real problem was that while sitting for such long periods of time , water could collect in the main tanks and basically rot them through on the deepest points. This is one more reason to fly a plane at least one's a month. That way you drain the water and also when up flying, the shaking and whirling in the air drives the water out of its corners and with any luck it will get pumped up into the header tank from where it can only escape into the gascolator. (My theory - I am proud of it). Have an eye on the airframe, engines are replaceable - fly often.
