So it sounds like it takes you about as long as it takes me to finish to job completely. I've heard that there are a couple of classical guitarists out there who don't use their nails and are still well respected and get decent sound. I've thought about it, but haven't yet just cut them all together.
As for the sandpaper made for guitarists, I believe it's the 500 grit I was refering to. They sell it in the Rosewood Guitar (the local classical guitar center and one of the oringinal on line stores).

I'll say Ana's hot!! She can play as well!
