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. ## Frequently Bought Together - Flex Glue, Super Strong, Transparent, Rubberized Waterproof Adhesive, Works Underwater, Use on Pools, Showers, Outdoors, Concrete, Brick, Pavers, UV Resistant, 4 oz Squeeze Tube, Clear, 1-Pack - Flex Glue, Mini, White, Super Strong, Rubberized Waterproof Adhesive, Works Underwater, Use On Pools, Showers, Outdoors, Concrete, Brick, Pavers, Masonry, and UV Resistant, 0.75 fl oz --- ## 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/148012616-flex-glue-rubberized-waterproof-adhesive-clear-4-oz-tube-1](https://www.desertcart.sg/products/148012616-flex-glue-rubberized-waterproof-adhesive-clear-4-oz-tube-1) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-01*
