First off this is not another thread about everybody's favorite oil to condition their rosewood or ebony, etc fingerboards. I have tried several "oils" and have my favorite to condition a fretboard. I've read a number of threads here and on other forums about folks who want a nice slick rosewood fretboard. There's folks who use steel wool or high grit paper and a conditioner, some who say just play it and it will get that way, etc. I'm sure they all work. I've also read about the views on putting a finish on a rosewood board (most say it's not needed or is detrimental). What I want to find out is anyone's experience with Behlen Fingerboard Oil. In reading the description, it does not sound like a conditioner but rather some type of sealer (or finish )to lock in moisture. Here is the description...Fingerboard Oil is ideal for preserving the feel and appearance of woods such as rosewood, ebony and similar woods used on stringed instrument fingerboards. It penetrates unfinished wood and dries hard; it does not become tacky when exposed to heat. Periodic reapplication will keep your fingerboard from drying out and in tip-top shape. It says it dries hard which sounds like a finish. The fact that it says periodic usage would concern me about build up but Behlen's is trusted brand for high end instruments so I would think that doesn't happen. Any users out there? If so, what results did you get versus normal conditioning of a fretboard? It sounds like something I'd be interested in if it can create that worn in slick feel on a newer rosewood fingerboard. Thanks!
