Abstract
A composite panel includes a mold surface, a layer of gel coat applied to the mold surface, a wet laminate containing a resin applied to the layer of gel coat, a substrate of lauan or another moisture-carrying or moisture-absorbing material placed on the wet laminate, and a layer of a bonding promoter provided at the interface of the substrate with the wet laminate, additional to any amount of promoter(s) present in the resin of the wet laminate. Without previously curing or drying the layer consisting essentially of the bonding promoter in the solvent, each of the wet laminate, the bonding promoter, and the gel coat are simultaneously cured.
