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
