There are may grades of vinyl... the 'indoor' is designed to by placed on wall or window surfaces and are have a manufactures guarantee that they can be quickly and safely removed from the surface within 3 years without damaging the applied surface. This is great for 'rental areas' that limit what the tenant is allow to do to design and personalize their apartment.
The 'outdoor' grade can be applied to any surface which will be subjected to the weather elements and/or car wash... the vinyl we use is factory rated for lasting a minimum of six years.
