Review: Worked perfectly - Fixed a loose window on a Renault zoe Review: 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. ## Features - Causes serious eye irritation. - May cause an allergic skin reaction. - Suspected of causing cancer. - Made in United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MS90CJU | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 45,192 in Automotive ( See Top 100 in Automotive ) 324 in Fillers, Adhesives & Sealants | | Colour | Clear | | Customer Reviews | 4.7 4.7 out of 5 stars (258) | | Date First Available | 2 May 2024 | | Item Package Quantity | 1 | | Item Weight | 42.4 g | | Item model number | ….. | | Manufacturer | Itw Brands | | Material | Silicone | | Part number | 81730 | | Product Dimensions | 9.53 x 20.19 x 3.05 cm; 42.52 g | | Size | 1.5 FL OZ | | Style | Compact | ## Product Details - **Brand:** Permatex - **Item dimensions L x W x H:** 9.5 x 20.2 x 3 centimetres - **Item weight:** 1.5 Ounces - **Material:** Silicone - **Style:** Compact ## Images ![81730 1.5 Oz Flowable Silicone Windshield & Glass Sealer - Image 1](https://m.media-amazon.com/images/I/71yWWUnJuvL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked perfectly *by P***P on 23 October 2025* Fixed a loose window on a Renault zoe ### ⭐⭐⭐⭐⭐ Review *by K***Y on 23 November 2025* I had a very big leak in the seal around my windshield that flowed water into the interior when it rained.
