Crack in Board
 

When I came off the lake I noticed a crack at the back end of the board. How do i fix it?

epoxy.

where is the crack is it all the way through the glass, or on the surface. A picture would help a lot. If it is big, remove the loose material and add a fiberglass patch to the top.

^ yeah, second the picture request. Would be nice to know the board make, also.
