I have a aluminum pan roof, that needs some help. This is on a summer porch, where the underside of the pan roof is the ceiling below. The underside, which has a white coating, is in bad shape. The color is gone in a lot (60%) of places, and the whole thing looks poor. I want to paint it, and am wondering what prep work to do, and what paint to use. Is it necessary to prime with zinc chromate before painting? Thanks in advanace
