The
first layer you can cut to the apex of the rail and then the second layer can
fully wrap over the board to the bottom. Just follow the outline of the board

fiberglass back a little at the nose and tail so there is not multiple layers
of fiberglass overlapping.This way the board is stronger to resist buckling and more
ding resistant on the rail
