Selecting the wood finish

Hi all,
I will be soon completing my next mountain dulcimer, made from Cherry (Top), African Mahogany sides and back, and Purple Heart Tuning Head, Tail and Finger Board.
I want a soft luster finish and after doing some reading, think Minwax Wipe-On Polly (Satin Finish) is the one to use.
Has anyone used this product, particularly on Purple Heart, and what were your results?
Thanks
