(more like a insulation)?, or stop a small draft creeping thru your window pane?** A: I'm sure you can. I have a waterwheel and trough. I sealed the trough, as it was leaking in several places. Even though water runs rapidly down the trough, I've had no leaking now for 2 years. I also used it to seal a leak on my ATV tir rim. The rim had a slight curve and wouldn't hold air. I sealed the sot that was leaking and it worked perfectly. **Q: I have a leak in my car trunk, can this be used?** A: It really depends on why there is a leak, but probably not. If it's the weather stripping around the trunk (that rubber tubing stuff), I doubt that this stuff will replace or repair that. That's the most likely reason you have a leak. The seal needs replacing. **Q: Can it be used on concrete?** A: Yes you can use Flex Seal on concrete. **Q: I would like to use this to refinish and seal up a mobile home bathtub. Does it clean easily? Will it hold up to the constant use of a bathtub?** A: It will definitely seal and refinish the tub. I’m not sure about easy clean up as I only used it on a boat but it should clean up nicely as it seems to be self leveling spray and is very smooth when completely cured ## Customer Reviews ### ⭐ Not good *by H***Y on 6 January 2023* Not good ### ⭐ Ca *by W***8 on 7 February 2023* Not worth it ### ⭐ Poor prodect *by A***F on 18 June 2021* Not useable ## Frequently Bought Together - Flex Seal, 14 oz, 2-Pack, Clear, Stop Leaks Instantly, Transparent Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More - 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 --- ## 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.jp/products/255083458-flex-seal-spray-rubber-sealant-coating-waterproof-clear-14-oz](https://www.desertcart.jp/products/255083458-flex-seal-spray-rubber-sealant-coating-waterproof-clear-14-oz) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-11*
