To test I used the cheap blue caulking gun - the one that often gives up when used with regular caulk from Home Depot (of course I have a commercial strength one too just in case). It pushed the adhesive with no effort. Also, it is worthy to mention that this product is very tacky & I was pissed off on myself not to listen to other reviewers to wear gloves and be careful - TRUST ME THOSE HORROR STORIES ARE REAL Submerge adhesive in very hot water for an hour or so, protect the area, wear gloves, punch decent size hole, install the applicator if needed and YOU are going to be satisfied. Review: sticks well remember to use gloves. - performed as i expected it dries / sets up to cure in warm weather. I used it as an under hood adhesive because the reinforcement panel was loose and it was most similar to the factory glue as a vibration dampener bonded real well. a 50 year old vehicle is expected to have issues. ## Features - Rely on the moisture in the air to cure. - Application process is quick and easy - Minimal odor - Country of origin: United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0182RGDP8 | | Best Sellers Rank | #43,970 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #101 in Silicone Adhesives | | Brand Name | Dow Automotive | | Color | Black | | Compatible Material | Glass | | Container Type | Cartridge | | Customer Reviews | 4.5 4.5 out of 5 stars (587) | | Full Cure Time | 24 Hours | | Item Form | Gel | | Item Package Quantity | 1 | | Item Weight | 8 ounces | | Manufacturer | Dow Automotive | | Material Type | Urethane, Adhesive | | Model | U-418 | | Part Number | U-418 | | Specific Uses For Product | Automotive | | UPC | 364875844245 | | Unit Count | 10.5 Fluid Ounces | | Viscosity | Medium to high | | Viscosity Level | Medium to High | | Volume | 10.5 Fluid Ounces | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Dow Automotive - **Color:** Black - **Item Form:** Gel - **Material:** Urethane, Adhesive - **Specific Uses For Product:** Automotive ## Images ![U-418 Beta Seal Glass Adhesive , Black - Image 1](https://m.media-amazon.com/images/I/71BnOEsehOL.jpg) ## Questions & Answers **Q: what gun size does it work with?** A: Hi this uses a standard size caulk gun with wide opening but this product requires at least a 18-1 thrust gun or better to dispense this product **Q: How many tubes do i need for one windshield?** A: Can you give size of windshield?

I submerged the tube in very very very hot water for an hour or so. To test I used the cheap blue caulking gun - the one that often gives up when used with regular caulk from Home Depot (of course I have a commercial strength one too just in case). It pushed the adhesive with no effort. Also, it is worthy to mention that this product is very tacky & I was pissed off on myself not to listen to other reviewers to wear gloves and be careful - TRUST ME THOSE HORROR STORIES ARE REAL Submerge adhesive in very hot water for an hour or so, protect the area, wear gloves, punch decent size hole, install the applicator if needed and YOU are going to be satisfied. ### ⭐⭐⭐⭐⭐ sticks well remember to use gloves. *by D***. on July 13, 2025* performed as i expected it dries / sets up to cure in warm weather. I used it as an under hood adhesive because the reinforcement panel was loose and it was most similar to the factory glue as a vibration dampener bonded real well. a 50 year old vehicle is expected to have issues. ### ⭐⭐⭐⭐⭐ Stuff is Sticky *by B***G on October 4, 2023* Worked great, and adhered to the window as expected. DO NOT GET THIS ON YOUR HANDS, IT IS VERY HARD TO GET OFF. I found WD-40 and Goof Off work well, but small traces are left. It has finally worn off. There is a lot in the tube. The spout to push the stuff out is oversized, so it does not fit into a standard caulking gun, you will need one with an oversized end for this, or cut it out with tin snips if you have a regular one. ## Frequently Bought Together - Dow Automotive-U-418 Beta Seal Glass Adhesive , Black - Dow Automotive 5504GML10 Beta Prime Glass Primer, 10 mL - Non-Heated Stationary Back Window Back Glass Replacement for Dodge Ram Pickup 1500 2002-2008 / 2500 3500 4500 5500 2003-2009 --- ## 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.hr/products/90524033-u-418-beta-seal-glass-adhesive-black](https://www.desertcart.hr/products/90524033-u-418-beta-seal-glass-adhesive-black) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-13*
