I've decided my course of action on the boat I'm restoring re: redoing the faded anodized aluminum (wet sand and polish w/ Alumiguard), but I also have some fittings that were powder-coated but have most of the paint flaking off. After sanding down and cleaning, what's the best paint to use to repaint? And do I have to prime? If so, with what?

Thanks!

Try a two-part Polyurethane paint it sticks almost anything.
