I recently ordered an Allparts TRO-V from Koko Tele (member/vendor here). It's not the fat, but is still a little more meaty than my other Tele's. I had him do a complete job on the frets, roll the edges and install a nice bone nut. I hit it with some steel wool then 10 coats of Tru-Oil. I used a couple of coats of Howard's Orange Oil/Carnuba Wax (contains no silicone) on the rosewood. I guess time will tell on the Tru-Oil. Primarily used for gun stocks. I would have to assume a gun stock will see a lot more environmental extremes than my Tele neck. With or without a sealer. Note: I have no affiliation with Koko, except as a satisfied customer.
