This stuff WORKS
I was skeptical about how much this stuff actually helps with 3M tape, but man, was I proved wrong.There’s a rubber seal that is supposed to be secured to the inside of my rear windshield to seal the 3rd brake light, but was designed poorly. Absolutely nothing could hold this seal to the glass. I tried every kind of double sided tape imaginable. Either the weight of the light or the heat from the car would get it off. This adhesion promoter and 3M tape finally was the thing that did it. So far it’s been holding for months. It works better than I thought it would. It dries in about a minute and is ready to take adhesive. So far I’ve secured that impossible light and my wing with the stuff and everything is still holding strong!

Worth it just to be safe
Had to replace some fender flare that were falling off my truck. Seems to be a factory install issue. So far so good with the new tape and this adhesion promoter holding strong. Can't hurt to use just to be safe

Golden standard of adhesion promoters
Not much to say they work as intended, though from other brands I found this one tends to be the golden standard.
