Re: Cleaning/Polishing Portlights
Kelleyg - Please see reply # 9.
These are definitely cast - and they are not SS (cast stainless? - no).
Cast aluminum should not be powder coated - it does not accept this type of finish, the heat pushes out trapped air that creates air bubbles and destroys the finish - I have tried this and it did not work, it was hell to remove the coating after the failed attempt. Polish and re-anodize or paint as explained in reply 9.
