Permatex Glass Weld Premium Urethane Windshield Sealant, 10.5oz

Overall: used it to fix the rear window on my soft top convertible. No leaks, super strong! Tips/What I did: - Back window was starting to fall in on my 2006 Ford Mustang. Pretty common issue but its a simple fix. - This stuff is strong, so have a reliable caulk gun! Used a cheap plastic one at the start, and it broke. Got a more heavy duty metal one and it was great. - Heat gun (or even a hair dryer) will make it easier. Heat up the weld so it comes out easier. - For the convertible top (depends on your situation but this is what helped me), start lowering it a little to give more slack in the back so the window is aligned correctly with the fabric. Suction clips help hold it into place. Used some towels to keep it pressed in from the inside. - Bead the weld to the rear of the panel line with a fine line. Press down firm when youre done and use painters tape to help secure it. - If you get some where you dont want it, wipe it away ASAP. Pain when dried. - Let it sit for 24 hours and its held up ever since.

Used this to adhere the top window track for the sliding rear window on the back glass for my 2015 F150. It is plastic to glass. The product is holding the track extremely well and I am very pleased at its strength. The product is hard to squeeze from the tube, so I would warm it up to make it easier to use.
