I just completed three nodeless rods (6ft, 2wt, 2pc) this last winter, using Gorilla Glue as the base surface finish. I followed up the GG with a couple coats of wiped on Birchwood-Casey Tru-Oil. Love it. I don't have and do not want to have a dip tube, so I think the GG and Tru-Oil will be my Go To, until I try something else and like better. Don't have good close up photos to share, but hope to have them soon.
Intended to make just one rod, but was having difficulty hitting the dimensions I wanted, so made a lot of sections, turned out enough for three. Two turned out closer to 3wt. My primary customer bought two (walnut reel seats, his choice), including the one more like the target 2wt.
