Is as advertised and seen on t v. I was skeptical but other than it being kind of a one time use due to it drying out. It was great. Just make sure you use it all. ### ⭐⭐⭐⭐⭐ It really works! *by S***T on August 10, 2026* It really works! It’s incredible! Highly recommend for water leakage! Not for plumbing! ### ⭐⭐⭐⭐ A little expensive, but it does the job. *by G***R on April 6, 2026* I used this on a steel trash can that I store bird seed in. The top had a gash in it and no matter what I did, water would get in and ruin the seed. I hated to throw it away since that was the only problem. A can of this, and the problem was solved. It's a little spendy for the amount you get which is why I removed 1 star. But there's no question it works good. My only other gripe is that it takes a long time to set up and dry. So if you can keep your project level and dry for 24 hours, that will go a long way to helping it cure. I just used a disposable paint brush to apply it and I kept the now hard brush for future applications. It's fairly durable depending on what you're trying to accomplish. I tried using it on the feet of my deck chairs hoping it would save wear and tear on my deck? Not a good idea, it just fell off after a couple of uses. But for sealing, this is a good product. ## Frequently Bought Together - Flex Seal Liquid, 16 oz, Clear, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - Pro Grade Paint Brush Set - 3-Pack - 2" Angle Brushes for All Latex and Oil Paints & Stains - Home Improvement - Interior & Exterior Use --- ## 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.kr/products/31879158-flex-seal-liquid-rubber-sealant-coating-waterproof-clear-16-oz](https://www.desertcart.kr/products/31879158-flex-seal-liquid-rubber-sealant-coating-waterproof-clear-16-oz) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-31*
