The windows work well and the seal seems OK. I did however take a couple of extra steps during my install to assure a water tight fit. First of all I used a bedding compound to attach the window frames to the truck. The instructions say to just use the two sided tape on the frames and then the window seal also works as a seal for the frames. I didn't like that and I am glad I sealed the frames before attaching the window seal. I have heard that someone did have a leaking problem most likely due to an improper seal placement. The window seal is the most important part of the install. The only other thing I don't really care for is the color/tint when looking out the windows. It matches from the outside but not from the inside. I would however recommend them and I would do it again. The air flow is good when opened fully and mine do not leak when closed..
Thanks...I'll be getting some next month. Although I think I'll have my buddy make glass windows that match the factory tint.
Once I get them I'll post some pics.
