Fills surface voids and irregularities, with a temperature range of -80 degrees Fahrenheit to 450 degrees Fahrenheit. This sealer comes from a trusted line of Permatex sealants for virtually any automotive sealing application, from windshields to vinyl tops to electrical connections. These well-known general-purpose and job specific sealants are cornerstones in the Permatex line. Review: Great for seam sealing tarps and tents - I use this flowable silicone for sealing the seams on my silnylon tents (SeekOutside Tipi, NEMO wagon top), it works great, cures within a few hours and keeps the rain out of my tent. I have also used this product to seal cook custom sewing silnylon tarps. The silicone doesn't crack and remains clear, I have had this applied on multiple tarps and tents for years with no issues or need to reapply. I assume it would be good for using with a windshield too, but my primary experience is with waterproofing outdoor gear. Review: Great to seal new headlight assemblies. 1.5oz tube is enough for 2 mustang headlights - I recently bought an 04 Mustang and decided to change the headlights rather than restore them. A typical problem noted on replacement headlights is leakage due to poor sealing. After seeing a recommendation ro use this silicone to go over the seal on the new headlights the day before installing them I bought a tube at the same time I bought the headlights here on desertcart. The silicone works great for going over the seams of the lights. There are many areas that you need to get the sealant down into a crevice to cover the actual seam and this worked great. It oozed into place easily and was not so runny to make it difficult or messy to use. I used a liberal amount on the seams so the sealant would cover more than a little and it would sink into the visible gaps from the poor job the manufacturer did on sealing. I did the job on my counter, with no dripping (YMMV as it does ooze slowly and depending on your light, it could drip) or spilling and no strong odors. The silicone settled into place and I was able to let it set for about 30 minutes until it was tacky and no longer oozing before turning the assembly over and doing the opposite side. I let it sit overnight to cure and installed the lights the next day. While it hasn't been long, I did take it through the car wash and do not see any signs of leaks. Great stuff and cheap to ensure your automotive lamp assemblies don't leak. ## Features - Forms A Tough, Waterproof, Durable, Clear Seal - Resistant To Weather, Extreme Temperatures, Vibration, Shock And Most Shop Chemicals - Flows Into Hidden And Hard-To-Reach Areas To Seal Leaks - Fills Surface Voids And Irregularities ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BKEBO0 | | Best Sellers Rank | #2,047 in Automotive ( See Top 100 in Automotive ) #7 in Body Repair & Restoration Adhesives | | Brand | Permatex | | Brand Name | Permatex | | Color | Multicolor | | Compatible Material | Glass, Vinyl | | Customer Reviews | 4.3 out of 5 stars 5,874 Reviews | | Global Trade Identification Number | 00686226817303 | | Included Components | Other Vehicle Parts( AUTO_PART ), Performance Parts - Underhood | | Item Dimensions | 8 x 4 x 1 inches | | Item Form | Liquid | | Item Type Name | Rigid Industries 46503 Fog Light Mount | | Item Weight | 1.5 Ounces | | Item dimensions L x W x H | 8 x 4 x 1 inches | | Manufacturer | PERMTX-LOCKT | | Material | Silicone | | Material Type | Silicone | | Model | 81730 | | Number of Items | 1 | | Part Number | 81730 | | Style | Medium Strength | | Style Name | Medium Strength | | Surface Recommendation | Glass | | UPC | 079340817302 686226817303 | | Unit Count | 1.49 Fluid Ounces | | Warranty Description | Warranty | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Permatex - **Item Weight:** 0.01 Ounces - **Item dimensions L x W x H:** 8 x 4 x 1 inches - **Material:** Silicone - **Style:** Medium Strength ## Images ![81730 Flowable Silicone Windshield and Glass Sealer, 1.5 oz. - Image 1](https://m.media-amazon.com/images/I/81PiaJkLW6L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: does it work on cell phones ?** A: I used the permatex 81730 flowable silicone on a cracked screen on an ipad. The corner of the ipad had hit a hard surface and fractured the corner without interfering much with the rest of the screen. I thought I would try the flowable silicone and see how well it worked. I was mainly hoping to keep small pieces from slowly falling out and destabilizing the rest of the glass in the corner. The flowable silicone works as promised. When applied it flows out over the affected area much better than regular silicone. However, it doesn't permeate the crack and basically sits on top of the glass itself. In my experience it did stabilize the corner but left a raised place above the glass that obviously felt like silicone and eventually began peeling off. I eventually had to peel it off the surface of the glass and I haven't as yet replaced it. That's all the info I can share about it... but that was my experience. **Q: can this be used to adhere the black strip to the front windshield?** A: 100%. It gets messy on your hands but it will do its job. I did on my windshield which had a gap and the air was coming in while driving... After sealing it.... It is perfect. **Q: Would this work on a car headlight housing to keep away moisture?** A: Yes it would as the silicone in it would prevent any water from getting in , also depends how big your Crack is . **Q: Will this work for a glass door that has a small crack (about 2 inches)?** A: YES---but it will run down if not masked off. Not perfectly clear. Any run down or thick area can be trimmed/shaved off with razor. The crack needs some open space for the fluid to penetrate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for seam sealing tarps and tents *by N***N on March 31, 2026* I use this flowable silicone for sealing the seams on my silnylon tents (SeekOutside Tipi, NEMO wagon top), it works great, cures within a few hours and keeps the rain out of my tent.

One guy came in with a tiny crack on the windshield edge that started to leak during a storm. I grabbed this, ran a thin bead along the crack, and it sealed up fast. The flowable formula makes it easy. I just tilt the bottle and let it run into the gap, no mess, no drama. It rides in our break room toolbox now so anyone can grab it before a road trip. Glad I have a simple fix on hand. ## Frequently Bought Together - Permatex 81730 Flowable Silicone Windshield and Glass Sealer, 1.5 oz. - Permatex 81158 Black Silicone Adhesive Sealant, 3 oz.
