I'm on the verge of getting this buzz electronics channel switcher/looper and I wan't to make it look a little more appealing and creative. I'm not very good with brushes so I'm thinking some kind of pen or marker. What kind would you guys suggest? Something that covers well and that lasts. I expect that I might have to clear coat it to prevent the colour from scratching off, so some kind of marker or painting pen that withstands coating chemicals as well.
