When dry, epoxy is very durable. Much less expensive than at big box stores. ### ⭐⭐⭐⭐⭐ Does what others fail to do *by J***. on June 11, 2026* This stuff does the job you’ve wished others would, but failed. Easy to mix, and easy to apply. Plus once it hardens, it remains bright white, perfect for repairing appliances with minor damage. The cap(s) actually work! That alone is reason to recommend this product. I will definitely buy it again. ### ⭐⭐⭐⭐⭐ A Must for Fiberglass Repairs *by J***. on May 10, 2026* Got a hole in the corner of my fiberglass shower pan. I used an oral syringe to suck up the mixed epoxy and backfill the hole for added sturdiness. Waited an hour, mixed a little more epoxy and used the flat edge of a caulk/grout silicone knife to level the top nicely. The epoxy is easy to spread, but thick enough that it doesn't flow downward or outward from holes your fixing. Great tensile strength is a plus when I might accidentally bump or step in this repaired area or put pressure on it cleaning it. Love that it resists water and chemicals, it being in a shower that is cleaned often. Great product. I can see me using this if I have any future fiberglass scrapes or holes. ## Frequently Bought Together - J-B Weld 50172 25 ml MarineWeld Syringe - J-B Weld 8277 WaterWeld Epoxy Putty Stick - 2 oz., Off White - J-B Weld 8272 MarineWeld Marine Epoxy - 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.co.uk/products/14367832-j-b-weld-marineweld](https://www.desertcart.co.uk/products/14367832-j-b-weld-marineweld) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-27*
