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

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!

Great product! It does exact as advertised. Be sure to wear gloves. You don’t want it get this on your hands or anything other your desired intended area!

used this to prime the glass in preperation for 3m window weld adhesive to repair a convertible back window that had seperated at a corner. So far so good, its been almost 2 months since the repair and the vehicle has been in temps ranging from 80 degrees to 30 degrees so far. It's be out in direct sunlight and in rain as well as beinfg washed and the repair is holding well. I'm very happy with the results.

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.

Worked as intended, no issues

Easy application and effective primer.

This is necessary if you plan to use 3m windo seal however read the long strip of instructions on the can including highly flammable and grounding the can, yourself, and work to insure static spark does not ignite it.

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.
