I work in construction and have been using glass fiber and carbon fiber wrap lately. I want to take a stab at glassing a fully shaped pu foam blank. I don’t know if this fabric is acceptable for a board though.
Is the fabric I have available to me acceptable to glass a board with? see link for more info

I compared it to the S2 Hexcel glass on one of my boards and it is slightly heavier and denser than that fabric.
Also how many layers of fabric does one typically use? I watched a video on swaylocks for glassing boards and it seems fairly easy, but I couldn’t pick up on how many layers the guy put on there. The only semi-difficult thing I foresee is putting in the settings for the fins and leash.
Any advice is appreciated.
