Adhesion Promoter 111, Clear, 250 mL Bottle, 4 per case

VHB was already the champion of refusing to let go. Then I added 3M Adhesion Promoter 111 and apparently created a permanent treaty between two surfaces. I changed my mind about the placement. The tape did not. A scraper, several tools, and some increasingly creative vocabulary later, the bond was still winning. Five stars, but measure twice.

I have a Tesla Y dual motor long distance. I have added all sorts of "enhancements" to offset the cheap design shortages - movable screen, splash guards, cockpit enhancements, top-of-steering stalk charger, rear LED lights for rear tow patch section and other rear lights (which has saved me from one rear-end collision due to bright attention-grabbing strobe effect I am sure - the guy behind me pulled into the left-turn lane beside me and we met eyes). I installed a set of the neoprene gaskets to reduce dirt penetration and noise but the attachment failed in many places. I ordered this product, and spent a lot of time using goof-off to remove every bit of old neoprene. I then used 99% ethyl alcohol to remove all residue of the goof-off.. I then liberally used this product to coat the metal of the Tesla where the new neoprene gaskets were to fit, and I went wider just in case. After several weeks I can confirm that the new neoprene is holding fast just as it should, thanks to this adherent. Many suppliers give little pledgets like alcohol swabs of this 3M solvent chemical - buying this is far better value if you are serious about making an install bulletproof. I recommend this product and would buy it again. Oh, and yes, the Tesla has been even more quiet as a result. Even if you don't have a T you would be good to use this to apply any neoprene gaskets in any vehicle, or doors of your house, or window gasketing of neoprene material.

Excellent product. I use it anytime I need to mount something. I wish I knew about this years ago. This bottle is a much better value than the single use wipes. I think this will out live me

Great stuff I used it to attach some fender flares to my offroad rig, cleaned both surfaces (fender flare and body planes) sandwiching a 3M double adhesive tape and they're are glued there, not even mud, heavy rain or rocks have made flimsy. Definetly will use whenever working with double adhesive tape
