Hello again from MusicianAtHeart.  We're happy to offer our Nut and Saddle Lubricant in a handy 2 oz squeeze bottle.  It doesn't sound like much, but this amount will last you a long time.  Perfect for lubricating nut slots.  Especially if you're a whammy player.  And great for saddles, open tuning heads, general string lubrication and corrosion fighting and whatever else you can think of. Being organic, it WILL NOT harm the guitar finish.
