Review: It does exactly what it is supposed to do - I was searching for 3M Adhesion Promoter wipes and found they were pretty pricey. Came across this pen as a suggested item and thought why not give it a try. It works folks.

It even helps with command hooks on tough to stick to exterior surfaces. ## Features - 3M Primer 94 increases the bond strength of acrylic and rubber based adhesive tapes.

Thanks! ### ⭐⭐⭐⭐⭐ It does exactly what it is supposed to do *by S***R on November 28, 2023* I was searching for 3M Adhesion Promoter wipes and found they were pretty pricey. Came across this pen as a suggested item and thought why not give it a try. It works folks. I use it for helping 3M double sided tape to stick to automotive glass that is in the sun all summer.... use it for automotive accessories. It even helps with command hooks on tough to stick to exterior surfaces. ### ⭐⭐⭐⭐⭐ Helps a lot *by J***A on March 2, 2023* As far as I am concerned this is manditory for installing anything with the 3M adhesive tape. MASSIVELY increases the holding strength, but makes it harder to install. The reversable tip is nice, just make sure it is snug as it can pop out if it is not and your product will spill. You will get a ton of uses out of this pen, WAY more than the bags of the single use applicators. ## Frequently Bought Together - ESI Pen Containing 3M Primer 94 - Tape Primer Adhesion Promoter .47fl oz / 14mL with Valve Action Reversible Applicator Tip - 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 Décor Home Office Logos Indoor Outdoor, Black, 0.025in Thick --- ## 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.gr/products/201940773-esi-pen-containing-3m-primer-94-tape-primer-adhesion-promoter](https://www.desertcart.gr/products/201940773-esi-pen-containing-3m-primer-94-tape-primer-adhesion-promoter) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-09*
