You just put a little dab of GG on a bit of folded paper towel and apply to the spinning part. Spin the part and polish until no longer tacky. The glue should be dry enough to re-apply in less than 1/2 hour. Half a dozen coats should be enough for a durable finish. Rubbed on GG is a common finish for bamboo fly rods.Beautiful work. I'm not familiar with using Gorilla Glue for finishing, how do you keep it from expanding or do you let it expand and shape and polish on the lathe?
