I am having a problem with the hardtop of my CJ-7. The problem is that I do not know how to seal the area where the lip of the hardtop curls around the top of the windshield channel. Without this area being fully sealed, there is a very large amount of air leakage whenever I drive it, and it is very irritating. It also leaks water when it rains. Could someone please let me know how to fix this?
