...for a Bomar/Pompanette hatch? I have the lense, and caulking, however, I noticed a gasket on the inside of the hatch. Is there a way to pull the old hatch lense out while leaving the gasket in place, or will I need to order a new gasket? I'm thinking of using a blade and carefully removing the old lense (by cutting into the old caulking from the outside) without damaging the gasket. I will check the archives but I'm guessing there isn't a whole lot there with regard to actual installation. Thanks in advance.
