If you are already using a CA/BLO finish, don't use Hut friction polish at all. If you decide to use the Hut polish instead of CA/BLO even on your stabilized blanks the pens will look dirty & dingy in a matter of days-months depending on how often the pen is handled and the type of wood. Your stabilized blanks will polish up nicely with the friction polish, but in time you will more than likely be unhappy.
If you are already somewhat successful with a CA/BLO finish, keep using that. there are other finishes that will give you long lasting durability besides CA. You can do a search in the finishing section to view the numerous posts.
