I think you misunderstood me. I knew there was a difference between the 2 polishes. I didn't know if the wax polish would build up over time though. On my Smith I use the pro formula on the body and the back of the neck (someone tell me if using it on the back of a BSREG neck is bad!), and up to now on the fingerboard as well. On my other (cheaper) basses I've used lem oil on the backs of those necks. I was just stating that I'll now start using lem oil on the fingerboard of my Smith as well. I'm gonna go with Ken's suggestion of using the white scotch brite delicate surface pads to clean with.
