There is a difference in lifespan and thickness. WILA protective foil is available in thicknesses of 0.8 mm and 2 mm. WILA protective cloth is made of a densely woven nylon cloth that is 0.3 mm thick. Protective cloth has a life cycle of as much as 8-10 times that of protective foil and is more flexible. Our advice is to use non-marking cloth.
