Resin swirl glassing | Experimenting with a new foam

In this video I build a board out of roof insulation foam. I'm using the resin swirl technique to glass this board. The result is a very pretty board, but will it surf?

When you had laminated the first glass fiber in thr bottom with tge shape concave, Haven't you had any problems without a vacuum? With spray the transparent and then you sanding?

I used a vacuum bag for the bottom just as a precaution. My camera ran out of battery, so that's why it's not in the video. But it is doable without one. You just have to be very careful and patient.

I used the spray paint after the vacuum but it had some small imperfections, dust particles and a bit of orange peel, so I sanded it with a very fine grid sandpaper to flatten the surface a bit more to make it shiny.
