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

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!

My use case was - I have some of those string lights, and bar (stick) lights that attach to the back of the TV and then I have a device where the lights change colors depending on what's on the TV. Ok, it's the Philips Hue lightstrip and a couple Play Bars. The strip and bars both come with mounting brackets or tape. The brackets allow the strip to go around the back of the TV (left and right sides and top), and the Bars have tape to mount as well. Thing is, the tape that you get from Philips doesn't hold very well, and the lights kept falling off the TV. The light strip is kinda heavy duty and doesn't bend well, and the bars I guess are a little too heavy. I even reached out to Philips and they sent replacement brackets that also didn't work. I also tried double sided Gorilla Tape. No dice, after a few weeks or months, a corner bracket, one of the side brackets, and one of the play bars would come loose again. It doesn't help that the back of the TV is very slightly 'rippled', meaning not sheer flat plastic. Someone online suggested these and honestly, they worked a treat. Clean the surface first, apply a bit of the adhesive, and stick your thing. So far, of the the places I applied it, nothing has come off yet. (One lightbar corner, one side edge, and one play bar. Using the applicator, a little sponge, is very easy, but there is a little quirk to it. You don't remove the sponge from the packet, you tear off the top part of the packet and hold it with the bottom part. You could use gloves also. While this way is fine, it also makes me feel like I'm wasting some of it because I never pull the applicator completely out of the packet. But the area I'm applying to is small and there was plenty in one packet for a couple areas. Plus, you can buy a small quantity of packets so it's easy to get an amount that you need to have enough, and also not to have a box laying around for years and years to come. Anyway- for my usage or anything similar- fully recommend. And actually, can't really thing of any other options that would work and not look awful. No word yet on what happens when I try to remove these brackets from the tv.....

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 used this to attach 3M hook and loop strips on top of spray-in bed liner while installing a BedRug in a Jeep TJ. I was a bit suspect, but it did work to "promote adhesion." The cost/product ratio was a little high. Each pouch (about the size of a wet wipe) contains a small, thin sponge that is soaked in the product. That is supposed to be enough to cover 150 square inches, which is just a little larger than 1-foot square—not a lot of surface area. I used 3 of the pouches for my application, but I did not cover anywhere near 3 square feet. Besides cost, my biggest issue was the durability of the sponge. In most applications it would probably be fine, but in my case, the sponges disintegrated very quickly when being dragged across the textured bed liner. Although it cost more than I think it should, I only needed a small amount, and I wasn't willing to invest in a larger quantity bottle.

GREAT

Ok I don’t review every purchase, but I felt I needed to review this. I have an adhesive mounted magnetic phone holder in my car that I really love, but it tends to come loose during the hot summer months. I was very frustrated because no matter how well I cleaned the spot and how hard I pressed the mount on, it kept coming off. I did a google search to find solutions and this product popped up. The mount stayed rock solid in place through the end of the summer and into the cold winter months. I’m very pleased that I’ve found a solution to the adhesive coming off. This product works exactly as stated, the only negative is there are no instructions the packaging how to apply.

This adhesion promoter is essential with getting 3M tape to bond well to surfaces. Make sure you stick it where you want it cause it ain’t movin easy after you use this.
