The laminates are preimpregnated and vacuum bagged to optimize the fiber to resin ratio and the adhesion to the E.P.S. core.The footwell is cored with divinylcell for added stiffness and durablility. West System Epoxy and AwlGrip paint are used. These are top of the line materials. These boards are light but strong, and will last for years if taken care of.
