Windshield Cowl weather strip leak

I've noticed that water gets in under the seal between the windshield frame and the body(cowl). I replaced the seal and still had the problem. Then What I found was that the fiberglass body is sagging in the middle, so if you are to lay a straight edge across from one side to the other it has settled/sagged about 3/8" in the center. I'm thinking of ripping the dash all apart to install some type of reinforcement channel under the fiberglass. Has anyone else ran across a similar problem? If so what did you do to fix it?

Can't speak as to a fiberglass tub, but on my steel tub I threw a 3/4" door foam weather strip on the cowl side and haven't looked back since.

I finally got around to it, installed a channel under the bodt that spans from one windshield hinge across to the other and supports the center. Sag is gone, and now the leaks are sealed.

Mine wasn't sagging but I wanted to make sure it didn't.

If you always do what you've always done. You will always get what you've always got.

Do you mean you replaced the OEM style gasket with some 3/4" single sided foam?

I've heard of this from other owners of fiberglass tubs. On my cj7 (fiberglass) it always leaked. When I rebuilt her I put a straight edge and it sagged about 1/8". I built it up with body filler when I did the body. That and a new seal and it hasn't leaked since. The cj8 I'm building now has a metal tub and it sagged less than 1/8" which I built up with filler also. The gasket usually doesn't seal this (I'm guessing because the gasket is so stiff) so you have to build it up with something.
