We're doing a total top-to-bottom paint job on our Hunter 34 and have removed a lot of aluminum hardware that was fastened with SS bolts and screws. Almost all of them had that white powder associated with galvanic reactions. When we get ready to reassemble everything what can we put on those fasteners to prevent the reaction with the aluminum? Most of the problem areas are on winches, and other aluminum that is anodized or bare and painting the items isn't very practical.
