3M 58526-case Adhesion Promoter 111, 1 gal (Pack of 4)

Somehow this product makes sticky stuff stick better to many surfaces. Not certain how it works, as it doesn't leave any kind of residue that you can see or feel, and just evaporates very quickly. I suspect it penetrates the material very slightly or perhaps just leaves a layer a few molecules thick.

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.

Adhesive promoter. What can I say? Definitely works. Use alcohol to clean your surface for prep. Then use a dab of this. Wait a minute or two then install. You wont be able to remove it after so be careful.

It's like alcohol on steroids. I cleaned all the gloss, wax and dirt off the top of the travel trailer before I use the 3M tape to adhere solar panels.

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

This is THE product for installing emblems and adhesive trim if you want them to stay put forever. Prep is key. Don't get it on any part of the paint that will show. Easy to use (disposable foam applicators are perfect for applying) and lasts forever. I've been using this for many years, but always the individual wipes. This little can will probably last me a lifetime.

For my purposes with EVA decking to gelcoat, 3m #94 primer was much better... If you can't tell from the datasheets which one you need, #94 is probably better if you are looking for a strong bond. this is probably more appropriate for sticking to painted surfaces

I decided to give this a try even though rubbing alcohol does the trick just fine. It's difficult to tell if it works better, but it definitely works very well.
