3M 08609 Window-Weld Super Fast Urethane Black Cartridge - 10.5 fl oz.

If you have to reattach the back window on a convertible soft top, this is the glue to use. It is thick and super sticky. Dries as flexible rubber. You have to prime the joint first with"3M Single Step Primer, 08682, Black Color, One-Part Urethane, UV Resistant" for best results. You also need to make sure you buy the suction cup clamps. In the end, this is as good as a job as if you took it to the body shop, except they charge you $600 - $1400 to reattach the window. Great product! Only downside, is this is a one time use product. One, it expires and Two, it will dry in the opened tube quickly.

Product worked as advertised. I have a convertible with a glass back window that had begun to separate over time. This product allowed me to restore the seal and prevent a costly trip to the dealership. It has been a few months now, and it is still holding strong.

ABSOLUTELY QUICK SHIPPING, ITEMS WERE AS DESCRIBED, I PRECIATE THE SELLER'S COMMUNICATIONS AND GLAD TO HAVE DONE BUSINESS WITH Y'ALL AND HOPEFULLY AGAIN SOMEDAY!!!

The product is great! 3M is a Top Notch company and I can always trust their products. Amazon, however, is not very reliable. I have ordered this product and it was received without the dispenser tip. I returned it and received a replacement. This too was without the dispenser tip. A call to 3M confirmed that the product should come with a dispenser tip. I further learned that Amazon is presenting that support should come from 3M, but 3M confirmed that they are not selling products directly to the public, which includes thru Amazon. 3M stated that they have been trying to get Amazon to stop having customers calling them for these sort of problems. Come on Amazon, get with the program! Don't take a great product and make it virtually unusable by not shipping all the parts ... twice now.

Excellent adhesive for auto glass and weatherproofing! Bonds strongly, cures fast, and remains flexible.

Highly recommend for reliable, high-performance results!

Used this to install a new windshield—set rock-hard in 15 minutes with zero leaks. The strong adhesion passed my car wash test immediately. Pro results at home
