I have made a bomb drop out of a steel tube to with a wide diameter to let the parachute people fall out easier and i didn't need to fuel proof it due to it being tin. I then decided to try a "pringles" chip tube because it had a smaller diameter and the coating inside will let the men slip out with ease. But what paint can I use, and/ or what can i spray on to fuel proof it?


also I am using a pin where i the plane on its side and the pin comes out, but i was thinking about using the lid along with a servo connected to a servo horn by a cable. Question is how would i hinge the lid to the tube?
