A method of protecting glass fiber reinforced products from the effects of weathering by applying a polymeric resin overlay to the product in mold. Conventional waxing of molds is eliminated. The mold is prepared by applying a layer of a lecithin solution, and the overlay is applied thereafter. A layer of gel coat is then applied to the overlay, the gel coat is reinforced and the overlay-protected product is demolded. The invention also includes a method for making an overlay-protected synthetic marble product.
