Good idea on the new lexan windows, I will try that too. so you tossed out the old plastic gasket that was around the plexiglass windows & used just the life seal sealant by itslef in the groove? was this a sloppy job? I know I could get a good seal with a boat caulk & no gasket, but I am afraid it will be really messy & get all over the new lexan. Merry Christmas & Thnx, Bob
