Fantasycart Fiberglass Cloth 4.12 Oz 41” Wide in 16.6 Yard Long

Great for the price. A little bit difficult to wet out but good lay up. Can't beat the price.

This is cheap fiberglass cloth, there is a reason it is 1/5 the price of stuff at boat builder shops, but with a few tips, it turns out fine.1) Tape the cloth with masking or painter's tape where you are planning to cut. This reduces fraying.2) This cloth does not like curves. Use it on flat surfaces, make your fillets generously large. Use a large rounded router bit to bevel outside corners.3) Slather the epoxy on, this stuff needs to have the epoxy really pressed into it.4) If you get bubbles that won't come out, relax, let the epoxy cure, then drill out a few small holes (1/16"-3/32") in each blister and use a baby medicine syringe to inject epoxy into the voids

Used this to repair my boat hull and deck with a marine grade penetrating epoxy and it came out beautiful. Will need some faring and sanding now, but I expect the final result to come out excellent. As opposed to chop strand I did have to apply some epoxy first and then stick the weave and then roll on some more epoxy to fully saturate the material. A little smoothing and stretching after that and it looks great! On a truly smooth surface you won't get bubbles. Spend the extra time sanding and cleaning before applying for a great result.

The product I received is not quite as described. What I received is not white but brown in color. All of the sizing has been heat treated out of the fabric making it look a dark toasted brown and very stiff. This is actually a fire blanket. a fire resistant cloth utilized in welding to control slag and embers to reduce the chance of starting a fire. They heat treat it in manufacturing so they do not smoke while being used. That precooking leads to the toasted color as it has quite literally been toasted. There is no silicone treatment that can be found on higher quality fire blankets so it can be used to fiberglass but not ideal if you want a clear wet out or are using a UV cure resin. The stiffness caused by the heat treatment is why everyone is having difficulty wetting it out. I would only recommend this for lay up on perfectly flat surfaces and only if to be painted or top coated. I Contacted the seller through there website to see if I would give an honest answer regarding the brown color and they responded "Hi, it was pre treated by epoxy, it should be better than the write color." I did not change a single letter. The brown color is certainly not due to contact with epoxy and I can only assume they meant to say either the white or right color as either would be right however "write" is wrong and so is this fiberglass cloths description.

Reading other reviews it seems other patrons don't know what they have. There are a few types of fiberglass weaves and the pattern of how the threads are compiled makes for different qualities. How it bends. How it takes glue. How it cuts. I been using this stuff for years, and it works great.

When I purchased this cloth I thought it would be plain weave. I received satin weave instead which is a higher quality than I expected and was the perfect cloth for my project.

Okay product. Does not hold shape well. Needs to be carefully laid on a large flat surface to cut. For thicker repairs use a heavier weight cloth like a biaxial 17oz or you'll be laying up multiple layers of this product. Overall it works fine. I use it on my sailboat repairs.

great price. nice weave. wets well.
