    Very informative video! I’m planning on using a 6 ounce cloth and EcoPoxy on a small rowboat I built using Glen-L plans. Does it matter which side of the cloth goes up and which side is down on the plywood?

    ok, so I have an 18 foot sailboat that I need to do a mast step repair where the wood is rotten and I want to replace with nothing but fiberglass. Build up layers. which is best for this project?

    Can I use this type of fiber to manufacture (the panels are flexible) Or is this a type of fiber that is not flexible?
