Here is a little done idea: blast it clean and leave the aluminum bare. Several advantages: no prep/paint issues, and the big one, you can see anything going on with the metal. Aluminum oxides to a nice patina gray color. Contrary to popular belief, it does not turn everything it touches black. My boom and mast are 'au naturel' for the last two years and no problems. Not for everyone... just thought I'd throw a diferent idea into the mix.
Is this true?
