Delivered as promised and in great condition. ### ⭐⭐⭐⭐⭐ Excellent product! *by J***S on July 20, 2018* The fiberglass cloth soaked resin without any issue and dried well. Excellent quality, the picture is exaclty same as the product I received. A 50 inch by 380 inch long fiberglass mat in a roll delivered which is exactly I was expecting. Very happy with the product. This fiberglass cloth is the way to go for boat repairs. In terms of what resin to use with product. Please refer to following information. Common fiberglass resins that you can find including polyester and vinylester resins work just well. Polyester and vinylester resins are both styrene-based and catalyzed using methyl ethyl ketone peroxide (known as MEKP for short), which kicks off the hardening reaction. Vinylesters are generally more resistant to water absorption than polyesters, which is why they are often used in hull blister repair. Both are very strong (most all fiberglass boats today are molded and built with one or the other); have good adhesive qualities when applied to properly prepared fiberglass; and are affordable for most boaters (though vinylesters do cost more). Generally speaking, when you’re doing a fiberglass repair, the adhesive qualities of the resin you’ll be using are a prime consideration. In this sense, polyester and vinylester resins are pretty adequate for most do-it-yourself fiberglass boat repair jobs, such as laminating fiberglass cloth into holes or cracks, or reinforcing an area (such as a stringer or transom knee) with woven fiberglass. Thickened polyester resin is also great for making cosmetic, non-structural repairs such as gouges and screw holes. For general fiberglass repairs, it's fine to stick with good old affordable polyester. All that said, epoxy resin is much, much more tenacious when it comes to adhesiveness, and it “sticks” great to boats made of polyester or vinylester. But (and this is a big “but”) polyester and vinylester don't adhere well to epoxy, so if you plan on applying gelcoat to finish the repair (gelcoat is a type of polyester resin), make sure you use polyester. If you try to apply gelcoat to epoxy, you won’t be happy with the long-term results. Epoxy resins also leave behind a slimy coating called “amine blush,” which needs to be cleaned off before you attempt to stick anything else to the surface. --- ## 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.jp/products/613754370-fiberglass-chopped-strand-1-oz-40-inch-x-4-yard](https://www.desertcart.jp/products/613754370-fiberglass-chopped-strand-1-oz-40-inch-x-4-yard) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-20*
