I used a plastic knife and some bug and tarremover and it worked great. I pryed off the 3.5 24 VALVE decal with the knife and then soaked the area with a mixture of goo-gone and the bug and tar remover. But it didn't let the mix dry. After the area was free of the adhesive I used and abrasive wax and waxed the area a couple times, it was that easy. Good luck!
