Here is how the process works. 1. Resin is less dense that fiberglass or any other cloth. 2. Therefore the cloth floats on top of the resin layer, [W/O peel ply] and forms a thick layer of cure resin just below the cloth making a heavier lay-up that is less strong because of the layer of resin.[as you add more resin the under-layer gets thicker] 3. By using the peel ply, capillary action draws the resin from under the cloth up to the layer between the peel ply and cloth, forcing the cloth closer to the structure being covered. You should add just enough resin to wet the cloth and peel ply. When you remove the peel ply you see the thin layer of resin.[ If the cloth wave is present, you didn't add enough resin].
