Pre-weathered waterslide decal signs are made using photos of real signs. Easily applied to structures and sign frames. Cut to fit with a decal scissors or hobby knife and apply using the manufacturer's instructions. Decals are printed on a clear or white decal base. For in-service signs printed on white decal film, simply trim the film to the edge of the printed area for best results. For best results with signs printed on a clear base apply decals to a white/light-colored area (you may need to paint the application area a light color to make them look less faded - it's a matter of personal taste) or directly to dark areas for a completely faded ghost look.
