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

Very good product. I submerged the tube in very very very hot water for an hour or so. To test I used the cheap blue caulking gun - the one that often gives up when used with regular caulk from Home Depot (of course I have a commercial strength one too just in case). It pushed the adhesive with no effort. Also, it is worthy to mention that this product is very tacky & I was pissed off on myself not to listen to other reviewers to wear gloves and be careful - TRUST ME THOSE HORROR STORIES ARE REAL Submerge adhesive in very hot water for an hour or so, protect the area, wear gloves, punch decent size hole, install the applicator if needed and YOU are going to be satisfied.

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.

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.

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.

Just like tar. Very sticky and can be extremely messy if you’re not careful. It’s still holding my sunroof glass in 5 years later

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.

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

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.
