save your money, use mineral oil. it can also lead to some humor (humour, for our british friends), when you walk up to the cashier, with 3 bottles in your hands. case in point, earlier this year, i needed to modify the opening in the gear of my m&m machines, to accommodate the requirements of a customer, who wanted to use mini m&m's, but only wanted it to dispense 10-15 of them. well, i was picking up some prescriptions at the local store, and walked up with a bag of mini m&m's, and a couple of bottles of mineral oil (since they also ring up small orders at the pharmacy). the pharmacy tech knows my sense of humor, asked what's up with the items, and (any time i am working with wood is a good time), i just smiled, and told her, good times adjacent. she just lost it, laughing, turning red, etc., and i accused her of going straight to the gutter, and explained what the customer wanted. so you see, mineral oil is a very good, food safe finish, and it is darned funny too.
