Review on High-Quality Auto Glass Sealant: Sikaflex P2G Urethane Glue with Primerless Adhesive (Pack of 2) by Richard Kuntz

Used to fix a cracked bumper after accidentally hitting a rabbit on a long trip through the mountains. Surprisingly, the poor guy did quite a bit of damage to my car. I put on gloves, cut the hose and smeared some onto the fiberglass mat, pressed it against the back of the bumper and then smoothed some more on the other side of the fiberglass. Hold on. It's probably stronger now than new. Like I said, it's very thick and I couldn't force it out with a regular Home Depot POS caulking gun. I had to cut the tube and pour it onto a paper plate and then use thick rubber gloves and fingers from there. This can be a headache for a window installer if they don't have a really good caulking gun and don't heat it up first.
