Also what about attaching something to the inside of the door by taking off the interior door panels? Or does it need to have contact to the outside surface?I don't, but I was in the Coast Guard and we had many aluminum boats and ships. It is very common to have a zinc anode on anything aluminum, especially in salt water. The zinc gives off it's electrons more easily, thus sacrificing itself for the sake of the aluminum. The issue is the doors and hinges are bolted together with steel fasteners before paint. There is a solid metal to metal interface between them. The different metals create an electrolytic reaction and the aluminum corrodes, sacrificing itself for the steel. The solution is to paint the door hinges and door skins before bolting them together. The paint should create enough of a barrier that this is no longer an issue. Same for the hood. All that said, the best course of action is to find an out of the way, obscure location, remove the paint to bare metal and bolt on some zincs.
