I get Water Leakage when it rains my head liner gets wet over the rear window on my extended cab, Just wondering if you guys have had any similar problems

yea i have- there is a little seperation between the window and the body of the truck- if u push on it u might be able to see it- i could- i had to get some clear caulk and put it on the outside- i tried it on the inside and it did not work

the rear window or side??

rear window-i have the sliding rear windows

so you just put it around the trim on the window? Just on the top or all the way around??
