well how about the exterior, how would i clean that and with what type of cleaning stuff

after every flight i spray my the outside of the plane down with Windex and wipe down all the oil and make it clean because
i heard if you don't do that the oil on the back elevator push rod can build up back there and cause flutter or major problems

then i heard your engine can rust very easily so whats the best way to clean it / Maintain it?

p.s. Yesterday i sprayed the engine down with WD-40 and then wiped it down "WAS THAT A GOOD THING" [sm=confused.gif]
