Just what I needed to laminate onto some fiberglass tube that was lightly smaller diameter than I needed. Used it with West System epoxy resin/hardener and rolled it up on a piece of plastic bag taped down to my workbench.

This fiberglass mat works as expected. It's my first time doing any fiberglass work, but I'm learning and improving the more I do it. I am using a double layer of this matting to rebuild the rear fenders on my van and it's doing the job....slowly due to me being a newbie at this stuff. It appears that it's best to use smaller pieces to cover the area and build up several layers over time. I still have to figure out how to bend it around sharp corners but that is probably an issue with any fiberglass mat.

Used this to repair a badly cracked fiberglass panel in my garage door. I can't believe how strong the repair is.
