Thanks for the tips, this might be just the thing once I get the bottom done and start working my way up.
Someone has re-painted a lot of the topsides, and even some of the hull, with who-knows-what. That includes some painted wood, fiberglass and aluminum. Some of it needs to be redone soon, particularly the (previously varnished) wood.
And of course, the colors all have to match, so I was hoping to find one paint that can do all three types of surfaces.
Does this seem like a good application for Rustoleum? Do you buy it in regular big-box home supply stores?
