The glassing process involves wrapping a board in fiberglass then applying the least amount of resin possible so as to not make the board heavy. The fiberglass makes the board strong while the resin holds it together. This bloke doing the work is former touring pro Matt Branson. He wanted us to point out that he usually wears a mask, just not when the camera is out.
A good glass job is just as important as a good shape and nobody does it better than Branno. These boards will dry for up to a day depending on the temperature and humidity.
