Thanks very much for the article quoted above, very useful.
I have used Liberon finishing oil extensively, and have learned much along the way. I refinished a Tacoma acoustic guitar with the dreaded finish rash, where the poly coat actually detached from the body.
I put the Liberon oil on in about twenty coats, but did not wait long enough between coats. The finish was sticky, and remains so on the neck, even after about three years.
I used it to refinish a Jazz Bass neck, applying three very thin coats. It was perfect.
