Now that your boards have been clean and primered your ready to set them up. Each panel will require weight in different locations to remove the distortions. Set up your weights, in this case I used concrete blocks, so that all of the distortions are removed. Then lay down your fiberglass. I found it best to use fiberglass mat verus the weaving material. The mat material seemed to be stronger because of it\'s multi directional fibers.
