I have 8 x Lewmar 1RE portlights on my boat. The outside outer frames are painted alluminium. The paint is either bubbling up or flaking off on all of them. The boat is 9 years old. I'd like to get the outer frames re-painted. I know this will entail the removal of the port lights and then removing the outer frame to be re-painted. I'm sure i'm not the only person whose had this issue. Has anyone out there had the same problem, if so, how easy was it to remove the outer frames?
