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. This product is to be cut with the design facing up, DO NOT MIRROR. Use of transfer tape is required to transfer the cut designs onto your project blank..
