    Reviewed in the United States 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.

    4.0 out of 5 stars Good quality fiberglass that sheds "needles" like a long-haired dog.
    Reviewed in the United States on March 10, 2024
    Verified Purchase
    I found this to be a good heavy duty fiberglass. It is consistent in thickness and lets light through evenly. I am a photographer and use it to place over light modifiers to reduce light output. Fiberglass can withstand heat better than most translucent light modifiers. With the slightest touch it sheds 3" "needles" in significant quantities, which are no fun to pick up. I am not sure why they cannot provide both sides with a transparent light glue that will keep the needles from shedding.
