This is a question for users of Fast Fret. Just curious if others who use this product regularly like it as much as I do? I rate it a 10. Keeps my strings feeling and sounding good for a long time. The strings on my two Nocasters, installed January, still sound decent -- and they are clean and shine. I apply according to directions. I stick part of an old cotton shirt in between strings and frets and slide it up and down neck, polishing both strings and frets. Eliminates any buildup of gunk. Then polish the tops of the strings with supplied cloth. Blow off lint with a bulb hurricane blower. To me, spray on products get gunk all over the place, whereas the fast fret can be applied to strings only. I keep it in a small jar and find that a new tube every few months works wonders. Do you like this product, too?
