Has anyone sucessfully repaired bubbling on aluminum port lights or hatches? I believe it is caused by electrolysis and/or moisture. I would like to enhance the appearance by removing the bubbling that was cause by overall neglect from the past owner. All hatches and port lights are of very high quality and other than the bubbling, they are all in very good shape, so I really don't want to replace them. And yes, the electrolysis has been addressed
thank you
