I finally received my special order after 2+ months and the guitar sounds amazing! However, immediately upon viewing the guitar I noticed a white substance on the bottom portion of the fretboard. My sales rep grabbed some lemon oil and wiped at it which helped but there's still some there as you can see in the second picture. My rep thinks it's compound or putty that wasn't wiped off the fretboard and that it should come off after a while. My question is how can I remove this and what is it?
