3M 4298UV Adhesion Promoter - Tape Primer 4 fl oz / 118 ml Bottle with 0.750" x 0.312" Felt Tip Applicator

Wow what a difference. This stuff makes a major increase on how the 3M tape bonds to surfaces. I would 3 times the hold strength. It worked way better than I thought it would. I used it for a Bedrug reinstall and tailgate weather seal on a new Ram 1500

This stuff works just dont get it on anything but what you need it to be on

Worked as intended!

Works very good, I was having issues having my lip kit stay on my bumper. One swipe of this after cleaning it real good. It stuck immediately and I couldn’t get it off.

Holy crap!! Apply this to the opposite surface of your project and it works unbelievably. Stick it correctly the first time because you ain’t gunna get a second time!! It sticks the first time every time.

This product was recommended to me by an engineer friend who uses it in conjunction with 3d printed parts on smooth surfaces & parts that need to hold weight. For my application I had issues with 3M VHB double sided tape carrying a modest load (15 lbs or so) which would fall off randomly or last about 3-6 months. After cleaning the surface and priming with the promoter I can already see the difference in the strength of the bond.

good stuff, really helps adhesion on carbon parts with adhesion tape

Good stuff! If you need it, then you know! Very functional, dries fast and is relatively easy to use. Much better value than buying individual pack but will dry out if you dont replace the seal under the cap due to the felt tip.
