Fiberglass Cloth Tape Non Adhesive Fiberglass Repair Tape Plain Weave Fiberglass Cloth Roll for Joint Repair, Reinforcement, Resin Saturation, Heat-Resistance, Insulation (4 in x 99 FT)

Good value, easy to use. Added the fiberglass to some G Flex for a Canoe. Held well.

detailed description wrong about thicknesmaterial listed glass plus a few others results in confusion about what you will receivefound o lot of chineese vendors having deceiving descriptionsquestionable lengththe thinness make it very flexible but need a lot of layers yo build up sufficient strength

Works well for patching and reinforcing areas that need such. I used this to repair my truck headliner board where I used to have an overhead DVD player. I reinforced both sides of the board with a single layer and it was very effective. Strong, yet lightweight.I recommend this cloth roll. 😄

I used this to repair a rotten place in the inner hull of my 1992 fiberglass boat. It worked well and was just what I needed.

I used this product in the corners of a plywood aquarium. It worked very well added a log of strength. I found this stuff easy to work with.
