I've done both front and back myself with the rope trick. Back window- no problems. Front leaks like a submarine with a screen door at right front corner only when it rains. I can spray the hose on it with the jet setting and no leaks. Right now it is raining and I have the corner covered and it is still leaking so bad I have a bucket under it. So obvious problem is not enough sealant on bottom? The corner where it's leaking is also the low point of the windshield because the car sits on a slight downward right slope driveway. Installed using the CJ Pony method with chalk strip inside the weatherstrip outer body channel with string, then pop window in and chalk like hell. Getting the bottom edge was difficult at best and I guess I did not get enough chalk from the tube/gun in there. So question- does chalking the the body edge opening first work better and then do the rope trick and chalk again? Has anyone done the method with weatherstrip chalked into body opening and then push/pry the glass in the inner glass channel?
