Review: Superior Glass - Heavy woven glass worked great, wetted out and built up fine
Review: Thick material - On most reviews I have seen that this product comes in a roll but this one came folded not that it makes to much of a difference for my use. The package was delayed in transit so not the sellers fault I gave it a five star cause it does feel like quality material and it’s nice and thick for what I’m using it for I will add more after using it with the resin.
