To see how they would turn out I stained some discard half wells grips with Minwax oil base stain, let them dry overnight and then 1 coat of Minwax Spar Urethane. Let that dry overnight and then buffed with fine steel wool. The final texture does not seem to differ much from that of the cork without any finish.
