sealing between windshield and trim

[tparker]

When I pulled the trim off the window it was full a rubberish compound. Also the edges of the windshield were rotted out. I am about to put the windshield back in and wanted to keep the water out as much as possible. Does anyone put anything between  the. window and frame, or in the trim? Byutl or urethane don't seem to fill up that space. What are others doing?

I've only used butyl tape to put the windshield in. If an area didn't seal I put some urethane sealer on a  spreader a work it in the gap. Never fill the whole area or put anything on the trim if you ever want to take it off without a fight! Test for leaks before you put the trim back on.

Butyl tape plus urethane sealer from the top edge of the glass down at about a 45 degree angle to the bottom of the window channel.

Lots of people tried to stop a leak by filling the channel with urethane or some other type of sealer. Don't do it that way.

My main thought was about water sitting in the channel, not so much a leak. Also I was curious why my trim was filled up with stuff.  I'm guessing it wasn't factory? It was like a rubber sealer of some sort.

Because some hillbilly back in the day smothered it all over to "fix" a water leak at the windshield.  My back window was the same way and I mangled the trim during removal.

@anlauto, when it rains, when I wash it, and when I cry when considering the cost for the next  part I need. I am not building a trailer queen and I don't mind driving the car in the rain.

@Dmod1974, It actually looked like a smart thing to do and was done very well. It wasn't hard to get off. It was a pain to remove it from inside the trim. After seeing the rot in the channel, I am actually glad it was done. It probably saved a lot of metal from rotting away.

I guarantee it was done to fix a water leak because the windshield channel was already rotten and wouldn't seal without it. My back window was no different. It's simply not needed if the windshield is sealed properly to begin with. And if rust proofing is the goal, there are far better products for that than RTV or caulk.
