Oracal 3651 Vinyl is one of the sign industry standards in printable media. It provides excellent print quality, permanent adhesion & great versatility for indoor & outdoor use. Intended for use on flat surfaces & simple curves, it can be applied to glass, metal, steel, aluminum, plastic, ceramic & fiberglass or any other smooth surface. With an ultra-smooth print surface & grey block-out backing, no color will show through when layering or applying vinyl onto a colored surface. Rated for 5 year outdoor use, we find it lasts even longer when applied properly to a clean smooth surface. For indoor applications you can expect an extended lifespan well beyond 5 years if proper surface prep & installation techniques are used.
