That's as bad as a guy that sat in on mine one time, formed blisters, popped them, then broke his fingers wide open and bled all over my bass. It took a couple of passes (wash, rinse, repeat) with a damp towel to get all of the gore offa my fiddle. The blood on the strings spattered the whole front of the fiddle from the vibration of the strings. Chee-rist.
Eeewww!

On one of the basses I used there was a real little bit of white nail polish (smaller than the tip of a pencil) on the side of the neck. It was at half and third position. It really helped me to get accustomed to the bass. When I felt ready I just took a blunt knife, and *gently* scraped it off.
White-out works well and is easily removeable.
