Mine leaks with a strong stream of water at the top of the angle where it turns from 45 degrees to horizontal. On a roadster, the weatherstrip in this area is hollow, but one can place a "filler" inside the weatherstrip. On mine, we're talking about building it up maybe .015" to make it touch correctly.

I found where mine isn't touching by putting a VERY THIN coat of oil (3-in-1) on the weatherstrip, closing the door and seeing from the outside where the oil didn't touch the inside of the glass. Does this make sense to you? Without the oil, you can't tell where it touches or not.

Then, I can insert a little sliver of foam rubber to build it up where needed.

Let me know?
