Review: A must have for dual sided 3M tape! - 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! Review: Good for TV lights that won't stick to the back of the tv - 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..... ## Features - 5 total, 2.5cc per packet - Use to increase the bond strength of all types of tape - Works great for low surface energy substrates like rubber and plastic - Same ingredients as 3M 6396 adhesion promoter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01G2BHLG6 | | Best Sellers Rank | #57,295 in Automotive ( See Top 100 in Automotive ) #95 in Body Repair & Restoration Adhesives | | Brand Name | 3M | | Color | Straw | | Compatible Material | Plastic, Rubber | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (1,677) | | Item Form | Liquid, Tape | | Item Package Quantity | 5 | | Item Weight | 0.01 Ounces | | Manufacturer | 3M | | Material Type | Plastic,Rubber,Sponge | | Model | Adhesion Promoter | | UPC | 021200275715 | | Unit Count | 5.0 Count | | Volume | 2 Milliliters | ## Product Details - **Brand:** 3M - **Color:** Straw - **Item Form:** Liquid, Tape - **Item Package Quantity:** 5 - **Material:** Plastic,Rubber,Sponge ## Images ![3M 4298 Adhesion Promoter, 5 Sponge Applicators (Choose 5 or 25 Qty) - Image 1](https://m.media-amazon.com/images/I/71Yj13Rb1HL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A must have for dual sided 3M tape! *by A***R on August 6, 2024* If you're going to install a car part that uses 3M double-sided tape, you need this!

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. ## Frequently Bought Together - 3M 4298 Adhesion Promoter, 5 Sponge Applicators (Choose 5 or 25 Qty) - 3M Super-Strength Molding Tape, 1/2 in x 15 ft, High Strength Double-Sided Adhesive, Permanently Attaches Side Moldings, Trim and Emblems to Interior and Exterior of Vehicles (03614) - 3M Double Sided Tape VHB 0.5" x 15.4 Ft 5925, Heavy Duty Mounting Tape, Foam Tape Strong Adhesive for Automotive Emblem DΓ©cor Home Office Logos Indoor Outdoor, Black, 0.025in Thick --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/32067796-3m-4298-adhesion-promoter-5-sponge-applicators-choose-5-25](https://www.desertcart.hr/products/32067796-3m-4298-adhesion-promoter-5-sponge-applicators-choose-5-25) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-19*
