Thouroughlly degrease the surface before applying the vinyl, heat slightly to get the vinyl to wrap round curves, and to set the vinyl off completley it needs to be heated to 80 degrees (heatgun), after it has been heated to this temp it will set off and you wont be able to manipulate it any more. If you dont set it off it will slowly peel/shrink back to its orignial shape after a few weeks.
