Steve is correct. BUT, allow me to add, the eraser works well on vinyl lettering and decals that are in good condition. This is a standard auto body shop tool made by 3M. You needn't buy the motor displayed in the link Steve supplied. You just need a variable speed drill and go slowly (low rpm). I removed several stripes from my 26.5 using the earser whell. No chemicals, no danger to gelcoat; it's magic!
Good wheeling,
