3M Single Step Primer, 08681, Black Color, One-Part Urethane, UV Resistant, 125 mL/4.2 fl oz

Bottle was sealed and fresh primer was inside. Worked as it should have.

In fact I needed the smaller bottle... it's just for one window and a few patching around the truck body so, this definitely, is a lot !!!Dozens of warnings about fire and breathing, so take it seriously, especially breathing and fire :-)Quality: it is great.It dries fast, especially on warm sunny day.It is BLACK, so be careful not to drip it - it sticks and stains pretty good.Sand the target areas.The "wool dab applicator" ? Not needed so, save your cash. A small 1/2 inch artist's brush will work great as it has to fluffy stuff.Use it outdoors !!! Or use a respirator if indoors and have an exhausting system running !

Great product. Superb primer to use for reinstallation of the chevy truck rear window.Next day I learned that window failure results from headrest pressure in the glass- Who Knew?

This primer is the bonding agent that allows the window weld to perform to its full potential. The larger bottle was a waste since it spreads out very thin on application. Secondly, there is no applicator included. I used a small acid brush then threw it away when finished. No need for a special "dauber". Thirdly, after opening this product it has a shelf life of only 7 days so plan your work accordingly. Lastly. Use painters tape to mask the area then cover anything you do not want black. One misplaced drop and you will be spending a significant amount of time trying to remove it.

I used 3M Windo-Weld Part #08609 to adhere a plastic rail that came apart on my F150 rear slider window. It failed to work because I did not know about this 3M Single Stage Primer. This absolutely did the trick. I only gave 4 stars because it didn’t come with a separate applicator (dauber) that is needed to apply the product. I bought a dauber at Home Depot for $1.25 and it worked fine.

Great Price and Great Quality !

Do not open this till ready to use. Check the date on the bottom to make sure it is still good. Wear throw away gloves and a shirt and pants you do not care about. If you get this on anything it will not come off. Period. That includes your fingers and other skin.You do not get a dabber, you must purchase that separately. If you do not have a clue on automotive glass replacement, stop now and call a pro.This is the primer you need for use with 3M's 08609 super fast drying urethane. This is what you put on both the glass and metal windshield frame or glass frame. It promotes adhesion with the urethane as well as offering UV protection for the urethane.As well it will stop rust from developing on the pinch weld frame if you scratched the pint during windshield or glass removal.You simply apply this primer to the glass and to the metal area and allow it to set for between 5 to 15 minutes before you apply the urethane sealer and sit the glass. It is best to apply this primer, than get your urethane ready, by that time you are ready to install the glass.

Easy to use, made the repair to my F-150 rear window trim easy. Adhered to my window and trim piece, tried other products that didn’t work. I recommend this product.
