. Our premium finish doors are meticulously cut, joined and planed. We stain each door with the highest quality exterior stain product available, painting a base sealant material and then hand-rubbing two additional coats of exterior sealant. In short, the fit-and-finish of our Premium Finish - Grade III rivals the quality on the finest custom wood entry door. We have numerous stains including natural, cedar, teak, dark oak and mahogany and we've also custom mixed stain colors to match a custom's existing wood entry door stain. Wirebrushing and other custom texture options are available. If you want the very best, chose our Grade III Premium Finish garage doors.
