This waterproof vinyl is a 3.5 mil calendered vinyl with a semi-permanent adhesive. This product exhibits very good image quality and the matte surface eliminates glare. Ideally suited for long-term indoor and medium-term outdoor applications, it will provide outdoor durability of 3-6 months without lamination. The basic properties of calendered vinyl make it unsuitable for any application that requires conformance to rivets, irregular curves and indentations.
