These 1973-1979 Super Beetle Convertible Solid Vinyl Door & Quarter Panels with Door Pockets are constructed of masonite wood backing, which is an extremely rigid and durable material that is completely unaffected by moisture!
Combine that with super thick Enduratex Vinyl covering in a variety of colors and you've got this door panel set that looks new longer, holds up to wear, cleans up easily and retains its original shape!
