TotalBoat TotalFair epoxy fairing compound can be applied over properly prepared, and fully cured gelcoat. Follow all surface preparation instructions for cleaning the surface, sanding, and applying TotalFair.
*DO NOT apply gelcoat directly over TotalBoat TotalFair. TotalFair must be primed with an epoxy primer, such as TotalBoat TotalProtect, prior to applying gelcoat.
