I'm trying to avoid repainting my front door (it is gloss black). The door faces S.E. so it gets pretty intense morning sun here in SoCal, which is hard on the paint. So I am thinking of getting a steel clad door and having it powder coated. The offering from HD spec's galvanized and primed. Simply powder coating over this would be ideal. If the primer must go, ok, but if galvanizing is a problem...?
