I spruced up my well used, super glued, zip tied guitar case in just an hour. Lightly draw your design with chalk then paint it on. I used kids craft paint. To keep your painting on, apply several, thin coats of lacquer. I used the spray on kind. *Drying time is 2 hours between coats then 24 hours for light use so keep this in mind if you need to take your guitar out & about.
