Add Camber to Flat Board Using Fiberglass

I’ve just bought a 7 ply longboard that is flat, however I would like it to have a slight camber. Is it possible to add the camber by adding a fiber glass layer and bend the board while the epoxy is curing?

You could use foam on the sides and then grip over it. There’s even grip tape with foam all ready in specifically for custom concave but I can’t remember what it’s called.

I believe you are talking about the concave, I want a camber board. This picture should explain it
