3M Single Step Primer, 08682, Black Color, One-Part Urethane, UV Resistant, 30 mL/1.01 fl oz

If you have to reattach the back window on a convertible soft top, use this primer and "3M 08609 Window-Weld Super Fast Urethane Black Cartridge - 10.5 fl oz." adhesive. 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! For this product a little goes a long way. This small container is enough for any window and you will still have tons left over. Make sure you also buy some daubers. Wear gloves and old clothes, this product will stain everything it touches. But if it drips on the window, just let it dry. It will come off the window easily with a razor blade.

Used this to create a better surface for adhesive to stick to on a convertible window repair. It was easy to use, went on quickly without mess and dried quickly as well. I gave it roughly 30 minutes to dry and that seemed to be more than enough.It's black so make sure you understand that before buying it. In 99% of applications the color wont matter but I can see a few with lighter colored cloth tops that might not like it if they mess up the application. Ultimately it wont be showing if done right so the color matters little.I used a makeup brush that my roommate didn't need to apply it because I didn't have any other brush available, and that worked perfectly. The adhesive stuck to the glass and the cloth and everything is working fine. The container is a metal bottle with plastic lid, and a small mixing bead inside. It was not difficult to open and does not leak. If anything changes like it separates or fades or something I may update the review, but for now, 5/5 stars!

Good product, terrible delivery, but on time. I hate it when delivery guys, who are probably 60 years younger that I, can't even make it to the agreed upon delivery to the front porch. I will have to get to my walker and hobble out to the mail box again! Thanks so much.

I fixed my 2004 Miata top myself. this was my first time doing it. This product was recommended in many YT videos I watched during my research and it paid off. I got it done in a few hours, something that could have cost me lots of money. I'm happy... as long as it lasts.

The product performs great, but for the amount of money paid for it, don’t send people expired goods. Luckily, mine was within a couple weeks of the date and I still Felt comfortable using it but I just think it’s wrong to do that to people, I’m sure most would be very upset. Other than that, it’s 3M…. You can’t go wrong. It does the job extremely well, like everything else the company makes.

Exactly as described

Used this to prep a glass window in a convertible top. Glass was separating from the canvas. I didn’t think it was fixable or would work. Watched videos on YouTube. Did what they said. Now it is better than factory. Totally watertight seal. Used this primer and 3M windo-weld. You can see in the photo where the previous owner used duck tape (that didn’t hold) instead of fixing it properly. Fix it right and keep your car dry. The adhesion and performance is shockingly good.

Primer works well. Does not come with dobber so had to run to get one at the hardware store
