they're new and I decided to use my new fast fret on them. The fast fret didn't have any oily stuff coming off it, isn't that supposed to happen? So I rubbed the fast fret really hard across the strings, and now they're rusty looking in places and really hard to slide on
never heard of that happening before i use that stuff all the time
someone has pulled a prank on u and replaced your fast fret with water
all of this happened in the course of about an hour
Lesson: Don't use fast fret on new strings?
is fast fret used for fret boards or strings?
