This would be the case at the pressure at this depth such that the polystyrene is compressed to a much higher density. Best of luck with the joints holding. **Q: Will this glue fibreglass to wood?** A: I`m not quiet sure about fiber glass, but it sectinatly sticks all metal that I have used. Like S to a Blanket. **Q: The top of the black tube got glued shut (no thickener on it), opened it with pliers & it has a leak now. is it ok to store sealed in bag, keep using?** A: Probably not **Q: Stainless steel to stainless steel** A: I glued cast iron to cast iron because you really can't weld cast because extreme heat would fracture when it cools. So I used this with clamps set for around 3 days and it worked perfect. Regarding stainless Steel to stainless Steel you can get it welded by a good blacksmith and the welds sanded down. Yes you can use this bur you would have to clamp tight and leave for 2 to 3 days. ## Frequently Bought Together - J-B Weld 8281 Professional Size Steel Reinforced Epoxy - Hardener and Steel Pack - 10 oz - J-B Weld 8267 SteelStik Steel Reinforced Epoxy Putty Stick - 2 oz. - J-B Weld 8276 KwikWeld Quick Setting Steel Reinforced Epoxy - Dark Grey 2 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.in/products/51951594-j-b-weld-8281-original-cold-weld-epoxy-dark-grey](https://www.desertcart.in/products/51951594-j-b-weld-8281-original-cold-weld-epoxy-dark-grey) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-29*
