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!

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.

Used these in my camera bag for a trip to Alaska and Africa. Worked very well for keeping the moisture out of my camera and lenses. If I had a complaint, the only thing I would say is 50 bags is way too much.

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.....

I don’t even use the adhesive that comes in the package anymore I use this product it works quickly and makes the 3M tape adhesive even stronger about to purchase more for jobs I want to do on my car..

The sponge applicators worked very well.

Exactly what I ordered!

Ensures improved adhesion by preparing the surface 3m tape is intended to bond with. The product could not be easier / more straightforward to utilize. Even after exposing the 3M tape to temperatures below zero within one hour of installation there were no problems with adhesion. Just remember you only get one shot at lining up whatever you are using the 3M tape to adhere to. It’s best to use painters tape to outline exactly where you want to lay down the tape / product.
