I agree and have been saying just this on each incarnation of the forum. I'm not sure the fascination with 'oiling rosewood' among guitarists, but it's a common... right or wrong. If you have a rosewood board and feel the need to oil, perhaps something try a no-wax polish like 'endust' first.i've been told by 3 different luthiers that it is good oil ebony with bore oil, lemon oil is ok, but bore is better -- but not to oil rosewood as it is a very oiled wood naturally and adding too much oil can cause the wood to be more susceptible to change in shape, lifting of frets, and/or separation from the neck in extreme cases. obviously, one drop per month is not going to cause this, but too much oil can. i dont claim to know one way or the other, this is just what ive been told.
