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

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.

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.

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.

I used thus ptoductbyo apply aftermarket chrome accessories to our van. Each pouch had just enough in it to cover the areas needed. It sure makes a super strong bond as there is no repositioning at all. It cleaned the surface and made the surface ready. A must have for cleaning and prep for any auto tape

I use this after thorough cleaning, degreasing, and alcohol swabbing to bond 3M peel-and-stick adhesive on LED light strips to the underside of kitchen cabinets, for countertop workspace lighting. I've never had an adhesive failure on surfaces treated with this stuff.
