Review on Dow Automotive U-428 Plus Beta Seal Glass Adhesive: Superior Black Adhesive for Strong Bonding by Tim Larsen

Used to install the left front air vent on a 2008 Honda Civic. than twice the price. It holds the window and trim securely in place and does not leak. It was about 40F outside and I broke the plastic caulking gun trying to get it out. I borrowed a metal one, but still had to squeeze the bar when I pulled the trigger. I heated the (metal) glue tube with a propane torch and it improved the flow somewhat (at ambient temperature). Will definitely buy again if my kid is stupid enough to break a small car window again!
