I've had the front and back done. Seems like A-1 Glass or some other easy name did it, I looked but can't find the name of who did it.

I thought mine leaked too, as I was getting a bit too much fog on the rear glass on the inside, so they came out and added some more sealant or something.

If you're getting leaking in the trunk, 2 overlooked sources are the truck seal that is clogged with gunk in it, make sure that's clean, and the other source is around the brake lights. The seals go after a while and allow water in. You might be able to use some light silicone to help shore it up, or buy new seals. I think you could also have water coming UP into the trunk, so check some port holes down under if you get water in only when driving.

Good luck on it. Finding water holes are no fun. Very annoying.
