I was in a guitar shop on Friday and spotted some stuff called Fast Fret. I asked the bloke what it was and he basically quoted what it said on the container. I asked him whether it was any good and he shrugged in that way that guys in guitar shops do. I bought some and he didn't snigger at me in that other way that guys in the guitar shops do so I reckoned it was safe to try on my Eko.
I really like it. It does just what it says on the tub.
