3M 4298 Adhesion Promoter, 5 Sponge Applicators (Choose 3, 5 or 25 Qty)

Product works great. Basically, if you treat a surface with it and use double sided tape to adhere a product to that surface, it will never come unglued. This stuff is great. Also, Amazon got this to me in 24 hrs. Amazon rocks! Retail continues to fade away with this type of service. Well done again.

If you're going to install a car part that uses 3M double-sided tape, you need this! This adhesion promotor will ensure the 3M tape really sticks to the installation surface. Works on car paint, even on glass. I use it for installing spoiler, scoops, splitters, or window louvers. Highly recommend!

This product works great with most adhesives. I used it to attach Velcro tape to my pickup truck bed liner. Installed about two months ago and it’s still holding strong. Excellent quality and excellent product from 3M.

I bought a new truck that had a factory spray in bedliner. I put a Leer on it and bought the Ford bed carpet kit. The velcro pads would not stick to the bed liner until I used the promoter. It worked good but the 5 pads do not go very far and are very expensive for what you get. If I did it again I would probably look at a bottle of promoter but its even much worse for price but would probably go a lot further.

I've used this primarily to adhere a trunk lip spoiler and foam strip lip spoiler for my car via double-sided foam tape. Naturally these items will need to be able to tolerate the force from air resistance. Using this basically activates the tackiness of your adhesive substance, as if it is partly breaking down the molecular structure of the adhesive medium. The catch is that because your double-sided adhesive foam strip is partly melting in structural integrity, I highly advise you line up the item you're planning to stick on correctly in one attempt. If the foam grabs onto another surface, it will cling, and if you need to readjust what you're sticking on, you will stretch the foam tape out of shape and make your job much harder. The adhesion is still active, but the stretched foam tape makes it nearly impossible to stick back onto your surface. Get it right once, and it will last.
