Im hoping to add a little bit once every week or so.** A: lol...I assume your goal is to "cushion" the noise from your neighbors wind chimes.(?) In that regard, I'd say yes. the flex seal would do that. It leaves a rubbery/plastic sort of seal on whatever you put it on. But it might show-up a little glossy or change the color of the chimes in doing so. Would like to a bird on the fence watching that covert activity! ;) **Q: Does the clear color actually dry clear?** A: Flex Seal Clear does dry clear if you spray thin even coats, however if you spray very thick and multiple coats it might not be completely transparent. **Q: does the surface need to be "clean and dry" ?** A: I bought a can of this to seal a crack in a concrete laundry tube in my basement. The surface was dry, but not especially clean (I did nothing special to clean it). I sprayed the cracked area once, let that dry and then another light spraying. The water leakage that had occurred before was stopped. The stuff did the trick. **Q: I have a leak in the tank of a ceramic toilet at the inlet valve will this seal the crack?** A: I’ve used this to seal cracked toilet tanks and it’s held for over a year. I have wall hung toilets so super expensive to replace, this is a much cheaper alternative. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by on Reviewed in the United States May 18, 2026* This product works well. I used it to cover the tops of dock pilings. I recommend it. ### ⭐⭐⭐⭐⭐ Works as good as on TV *by on Reviewed in the United States May 18, 2026* I used this to seal a leak in my concrete fountain. I was a bit hesitant having only seen it on TV commercials and no one else's experience. I cleaned around the crack, sprayed 2-3 layers over it and refilled. It's been several months and no leak. ### ⭐⭐⭐⭐ For the right job, it's the tool *by on Reviewed in the United States April 29, 2026* Left no room for doubt that this is liquefied rubber in an aerosol. Be careful to get the Right Tool for the job. Check their "store" on Amazon- interesting discoveries there.For waterproofing / moisture barrier I would consider this again if a thin layer is adequate. May need to develop some application "technique" in some instances. My unusual situation involved some gaps that were worse than I anticipated. It's thin. Layering onto partially dry base layers to bulk it up did work but it's tricky until you find the way.I should have had silicone caulk on hand too but this seals hairline gaps nicely.With clear version, it's hard to see what's happening & to avoid waste or a running mess. Clogging is not a problem you'll likely have. As you might expect, liquid rubber involves intense solvents. You cannot over ventilate when using this. Plan ahead if using indoors. ## Frequently Bought Together - Flex Seal, 14 oz, Clear, Stop Leaks Instantly, Transparent 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, 1-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.sg/products/2594745-14-oz-clear-stop-leaks-instantly-transparent-waterproof-rubber-spray](https://www.desertcart.sg/products/2594745-14-oz-clear-stop-leaks-instantly-transparent-waterproof-rubber-spray) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-16*
