Holy hell. I've gotten 20oz, and it was hard to work with around bends... but man that stuff is sturdy. Takes a hellofalot of resin to impregnate.ive used 40 oz. mat on a couple of enclosures keeps layering to a min but is expensive as balls
How do you know if you should be using chop mat or cloth?? Is one for curves and one for flat?? Does one have more structual properties than the other???
