If you don't care about the uniformity and density of fiberglass fabrics, then this might work for you. It is a very loose and unevenly woven fabric with MANY defects. Fabric tension, missing threads, etc. The roll I received wound 3-4 inches from the end of the roll. So most of the width was practically unused. By God, the whole end of the roll was broken and dirty. It looks like the reel was on the other end and got wet at some point. I've wanted to use it for glazing remote control fenders, but I can't find a piece long enough without a noticeable defect to make even half a 20" fender. Obviously it's not intended for what I intended to use it for.
