Used a whole gallon on the floor of my pickup bed after I rhino lined it. Very difficult to brush and roll on. Ended up pouring it onto the bed and using the brush to just push the rubber around. It will be very durable when cured, just wish it was thinnable so you could use it in a thinner coat. Price is a bit high too. ## Frequently Bought Together - Flex Seal Liquid, 1 Gallon, Clear, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry - Flex Seal MAX, 17 oz, 2-Pack, Clear, Stop Leaks Instantly, Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More - Flex Caulk, Waterproof & Weatherproof Hybrid Polymer Sealant, Strong, Paintable, Indoor, Outdoor, Bath, Shower, Sink, Window, Baseboards, Door, RV, Roof, Wood, Auto & Marine, Clear, 6.6 oz, 2-Pack --- ## 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.tn/products/393013905-1-gallon-clear-liquid-rubber-coating-sealant-waterproof-flexible-breathable](https://www.desertcart.tn/products/393013905-1-gallon-clear-liquid-rubber-coating-sealant-waterproof-flexible-breathable) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-28*
