Can anyone recommend how to repair or replace the rubber window molding on our sportcraft boat?

Question

the molding shrunk and now leaks. all we can find is caulking in a tube - messy idea!

Answer 1

You will have to remove the glass from the frame. If it is held by rivets, you'll have to drill them out. Find new gasket rubber, and replace.

If the shrinkage is slight, clear silicone based caulk is a lot easier!
