Actually, the inside strip doesn't really make a difference. Both doors are leaking right at the mirror where the two pieces of weather strip meet at the corner. The water runs down along the window run channel inside the door panel. I can seal it with putty from the outside, for testing. Since this is a tough spot to get to what is the best thing to use to seal it up? This is driving me nuts, I have already fixed 3 leaks since I bought the car 2 months ago.
