Depending on what material is being used for the actual decal will depend on how well it will hold up. First clean the area with rubbing alcohol like stated above. then just apply the vinyl if its something pretty big and its being printed see if they can over laminate it... or you can just drive down to benton harbor i work for art & image.. we over laminate our products if its just the detroit D, very easy piece to do if you interested send me a PM
