I put a VW power window interior rubber that i' ve got from a friend that works at glasses car shop.It's a double rubber it seal's from the outside amd from the inside. I ' m sorry about my english. Will bear that in mind, I was just looking at putting a rubber grommet in it to seal the hole. What I meant though was have you put something on the rear screen for when it's raining so you can still see out of rear window Lol, I' ve forgot that small detail.
