I would also use a woodturners stick over the top of friction polish it contains Carnauba waxwhich I'm sure you know is the hardest wax a going Liberon Woodturner's Stick - Woodturning Finishes - Woodturning Consumables - Woodturning - Woodturning & Crafts | Axminster Tools & Machinery
If I may second the Liberon stick is my gofor choice with most every pen I make in wood the original stick for at least fifteen years is only part worn down yet I consider it a must have use it sparingly just a lightwipe and polish it can cloud if you jam it on.
