I ordered some adhesive reflective striping from StreetGlo online. I got a roll of 1/2-inch (12 mm) and a roll of 1-inch (25 mm) white/silver reflective stripes. They were applied using the "dry" method, which is directly onto the paint of the scoot. The wet method utilizes spraying a weak soap and water solution onto the area, then laying the stripes on the wet area.
I have no "before" pics, since our camera was hosed while I applied the stripes. Here are the after results:
