Hi Kick, I usually can do 2 guitars from one of those small bottles. After about 6 thick coats I revert to 50% mineral turps to 50% Tru Oil and that makes it go a lot further plus helps with levelling things out. To bring on the smooth finish and shine suggest applying with 1500 grit wet & dry paper as that helps to wet sand as you apply the finish. A great trick that takes a bit of practice to get right but well worth the effort.

Cheers, Waz
