Dow Automotive-U-418 Beta Seal Glass Adhesive , Black

Had a problem with my RV glued in windshield. The adhesive failed in the interface to the glass. I suspect the installer did not use the special glass primer. I cut as much of the old adhesive out using several different knives and applied the Betaseal. I was surprised how easy it came out of the cartridge using a regular caulking gun. It also was very easy to smooth out. The repair (originally thought temporary) is still in place today a year and 4000 miles later. So no need for a primer and my tip is to slightly warm up the sealant in a water bath if you are working in cooler temps.

Worked great, and adhered to the window as expected. DO NOT GET THIS ON YOUR HANDS, IT IS VERY HARD TO GET OFF. I found WD-40 and Goof Off work well, but small traces are left. It has finally worn off. There is a lot in the tube. The spout to push the stuff out is oversized, so it does not fit into a standard caulking gun, you will need one with an oversized end for this, or cut it out with tin snips if you have a regular one.

Used this stuff to repair my Mustang convertible top. The back window was beginning to separate out of the vinyl top in two places. I put painter's tape on the glass to protect it/for easy cleanup and used a caulking gun to fill in the gaps. I waited 48 hours for it to cure and it's still going strong five months later. Bought me time to save up to get the top replaced. Wonderful stuff, would absolutely use again.

performed as i expected it dries / sets up to cure in warm weather. I used it as an under hood adhesive because the reinforcement panel was loose and it was most similar to the factory glue as a vibration dampener bonded real well. a 50 year old vehicle is expected to have issues.

Had to reattach my car door window back to its mounts. So far everything is holding great with no signs of any issues. Stuff works like caulk but doesn’t come with the pointy nozzle so be prepared for that.

I got this to re-attach the sash clips on my daughter's car a year ago (January 2025 timeframe). So far, so good.

I bought this to re-attach the window clips on a car power window glass. After removing old adhesive and cleaning the area with solvent this adhesive worked great. After curing (about 24 hours) I tested the adhesion and seemed strong . I reassembled the glass into the door and tested the window and its good. I would recommend this adhesive. Time will tell how long it lasts.

Didn’t come with applicator tip, thought maybe I was just unlucky and ordered a 2nd one that also didn’t come with a tip. Returning both and finding something else. Should have read more reviews first to see that this is apparently a common issue.
