The surface of my graphics is as smooth as any others I've run across. It has a slight matte finish initially, but it was explained that was from being rolled up and the texture from the backing material. After exposure to the sun, it has assumed a shiny/gloss finish

The surface was prepped with a type of primer to increase adhesion around the edges. The leading edges were also overlaid with a clear tape layer to resist peelback from water pressure or grounding.
