I'm working on the horizontal stabilator skins. Today I was doing some priming of interior surfaces and accidentally scuffed up the outer surface of one of the aft skins. It's a V-shaped skin about 6" x 12". I know whenever my project goes to paint that it will be scuffed anyway. But, if my build takes a couple years, I don't want that piece to corrode. Should I just order a new piece or rivet this one on and just protect it with some wax? I'm guessing with a new part and shipping, probably <$50.
