I had previously used clear silicone that was for windows and bathrooms, but the windows still leaked. After removing all old silicone from under the edge of the black rubber window seals, I applied this product. One tube was sufficient to do both windows. After several heavy rains, I have found no leaks! This product works as advertised and is better than any other silicone sealer that I had tried. ### ⭐⭐⭐⭐⭐ Cheap, easy fix for a big windshield leak *by on Reviewed in the United States 23 November 2025* I had a very big leak in the seal around my windshield that flowed water into the interior when it rained. I squeezed this all along the crack above the top weather strip, and now there are no leaks. Completely surprised it worked so well and in only 1 application. I assumed it would leak and I would need to apply a second time at least, but this stuff is pretty amazing. I'm going to use it for other stubborn leaks as well. Well worth the money. --- ## 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/709998349-permatex-81730-1-5-oz-flowable-silicone-windshield-and-glass](https://www.desertcart.sg/products/709998349-permatex-81730-1-5-oz-flowable-silicone-windshield-and-glass) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-15*
