Here is a related question. My Imron-painted aluminum mast and boom has the
usual assortment of fittings and attachment methods typically found on a
twenty-year-old boat now on it's fourth or fifth owner. For the most part
the paint is in good condition, (and stainless bolts protected with TefGel
or similar) but here and there next to older stainless fittings, or around a
weld there are the usual smaller-than-a-pea pustules of corrosion. Sooner or
later I plan to have the entire mast repainted professionally but in the
meantime what is the best etch/prime/paint touchup method to minimize
continuing damage? I assume there is a more or less standard sequence and
bill of materials used by aircraft or aluminum boat maintenance shops. Any
suggestions re online or local vendors would be much appreciated.
