I am finally at the stage to apply a finish to two bamboo fly rods, but still haven't decided on which one to ultimately use. The rods are a banty and a SB 359-9 that will receive a new reel seat, grip, and guides. A wipe-on polyurethane or Birchwood-Casey Tru-Oil seem like the easiest as opposed to a spar urethane. However, what could I utilize to thin a spar varnish to make it a wipe-on to aquire the benefit of UV protection? Any input regarding experience with these types of finishes would be appreciated.
