Review: Love All Flex Seal Products - I tried the caulk and white glue before, and were very happy with how well they work. When I saw the glue in clear, I had to give it a try because white does not always fit the bill -- I don't want white oozing out -- clear is much better! The only thing I would like to see for all Flex Seal caulk and glue products is putting them in containers that can be used until the product is gone. Once opened, it is very difficult to squeeze and get out the product even after following the directions for closing after use. I have to use sticks and whatever else I can find to break the seal deep down to get caulks and glues flowing again after first use. The tube clumps up the product and dries making one unable to just open and squeeze to use. Review: Flex Glue – The Miracle Goo You Can’t Live Without - Ayo, listen up!

Reach out to us if you have any other questions about our products. We're always happy to help. Flex On!! 🖌 **Q: Does it work on foam? I need to secure a foam (sound proofing) headliner to the roof of my jeep. Will this hold for that and in the heat of a vehicle.** A: We haven't tested it for that specific application but it seems it should work. Flex Glue once fully cured withstands temperatures up to 200°F. Due to the number of variables involved in this application, I would recommend testing a small area first to confirm adhesion. Here are some friendly tips for best results: Before Use: 1. Start with a clean surface free of such things as grease, oil, dirt and algae. 2. Unscrew the cap and cut the nozzle to the desired length. During Use: 1. Apply liberally to one side of the surface to be bonded. 2. Apply firm pressure continuously for a minimum of 10-30 seconds for instant grab to take hold. 3. Object may be repositioned within 10 minutes of application if needed. 4. Product cures in 24 to 48 hrs. After Use: 1. Squeeze a small bead from the opening to form a plug. 2. This plug will cure, sealing in the remaining product. 3. Simply remove this cured plug or cut it off to reuse the product. Thank you for your interest in the Flex Seal Family of Products. **Q: Does Flex Glue work on metal?** A: Yes, Flex Glue is incredibly effective on metal surfaces. Please ensure the surface is free of grease, dirt, oil, or loose rust and apply liberally. Some applications may require bracing; however, Flex Glue takes about 24-48 hours to cure fully. Please let us know if you have any additional questions. Flex On! **Q: Will flex glue work on rubber mats that will be glue down to both aluminum/fiberglass boat hulls** A: Yes, believe it should, but it will be permanent. I have done a similar thing in my boat and I used rubber silicone and it worked great. Also, it is easier to replace if needed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love All Flex Seal Products *by P***K on August 23, 2021* I tried the caulk and white glue before, and were very happy with how well they work.
