Driving in the rain and getting peppered in the face with water after I paid a few hundred dollars for a windshield driving me nuts, I knew I had to do something. I ended up finding some rubber weatherstripping in a P shape from Amazon.
I put a strip of that on the top of the windshield and also on the the lip of the roof that hangs down. They now overlap, so I think I should be good. THe only thing that concerns me is that the 3M tape doesnt hold when bombing down road, the air current might grab the edge and pull it off. The 3M adhesive doesnt seem to be that strong (its probably not 3M).
Sorry, the pic needs to be rotated 90* clockwise.
I also used the same stuff to help seal the rear passenger door where the hinges meet the roll cage.
Shot is looking down at the top of the door to the ground.
