I don't personally know what "Un-do" is so I can't comment on it, but Hemee knows her stuff. You can also use WD-40, Liquid Wrench, rubbing alcohol or Goo-Gone. Soak the residue for a minute or two to allow the solvent to penetrate. Use a microfiber cloth to avoid scrathces. You essentially want a MILD petroleum based solvent. Please be sure to stay AWAY from acetone, laquer thinner or anything in these families (strength-wise). Please be sure to put some sort of wax on the area after you have cleaned too to protect the paint as the cleaner you use will also likely strip off any wax you had on there.
