For use with acrylic. Review: Works great, be aware of the size - Great thing to have if you are prepping for automotive body parts. I was replacing a side skirt on my car that had sagged, after I cleaned the area I wiped up and down the sills of the driver side with *2* of these (keep in mind the size!). The 3M sticky tape I used held very well after letting it "cure" for 24 hours against pressure. This promoter is not cheap and you have to get a lot of it for larger jobs, but it works very well and you will only have to do what you are doing once. Yeah, I could have skipped using this and just applied the adhesive after a good clean, but I would probably have to repair it again in a few years. Now I won't. Review: Working great - Works great for installing trim on my truck held securely in the intended position. ## Features - Sale Unit: EACH - Brand: 3M - Type: Primer - For Use With: Acrylic - Material Compatibility: Plastic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004TGJU2A | | Brand | 3M | | Customer Reviews | 4.4 4.4 out of 5 stars (167) | | Date First Available | March 23, 2011 | | Item Weight | 0.16 ounces | | Item model number | Adhesion Promoter | | Manufacturer | 3M | | Manufacturer Part Number | 70070698421 | | National Stock Number | 8040-01-618-0510 | | Product Dimensions | 3 x 3 x 0.13 inches | ## Images ![3M 4298 Adhesion Promoter, Sponge Applicator - Image 1](https://m.media-amazon.com/images/I/71GhCFE9XDL.jpg) ![3M 4298 Adhesion Promoter, Sponge Applicator - Image 2](https://m.media-amazon.com/images/I/71FWRiUS4IL.jpg) ![3M 4298 Adhesion Promoter, Sponge Applicator - Image 3](https://m.media-amazon.com/images/I/618JnUzrhgL.jpg) ![3M 4298 Adhesion Promoter, Sponge Applicator - Image 4](https://m.media-amazon.com/images/I/61x3D-k2bpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great, be aware of the size *by M***L on November 12, 2014* Great thing to have if you are prepping for automotive body parts.

I cleaned all the Mirror fragments off to back plate holder and cleaned the back plate itself with alcohol first to get any adhesive off. I then waited until the temperature was in the mid 60s so everything would cure properly. I then applied the 3M adhesion promoter. I gave it a few minutes to cure and then applied the 3M double sided tape along with the 2 double sided pads that came with the mirror. I then removed the front of the double sided tape and applied the mirror. That was Three days ago and the mirror is holding and working like it should with the electric control for adjusting the mirror without any problems. I give the applicator pad a thumbs up for a review. So far it's doing what it is meant to do. ## Frequently Bought Together - 3M 4298 Adhesion Promoter, Sponge Applicator - 3M 06384 Automotive Acrylic Plus Attachment Tape , Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/808441113-3m-4298-adhesion-promoter-sponge-applicator](https://www.desertcart.in/products/808441113-3m-4298-adhesion-promoter-sponge-applicator) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-09-11*
