I don't suppose you are in New England? There's a guy in Vermont who fixes leaks in jeeps. I know he travels to Massachusetts. I used to get four inches, yes four inches, in my 98 TJ after a heavy rain. This was back in 1999. It was leaking around the windshield, cowl, fresh air intake, around the antenna, drivers door and tailgate. Other than those it had no leaks. Anyway, he took care of almost all of it. Now I just keep a thick towel rolled up and stuff it under the inside of the door jamb for the small amount I get now. It might be a franchise thing...called Leak Doctor I think.
