There are some woods — generally described as “exotic” — that are so oily by nature that the oil finish may dry very slowly, or even not at all. Such woods are rarely used as a stock-wood but sometimes appear as forearm tips etc., and as such, as long as the natural oil remains, require no actual protection. Such woods usually take a good polish when buffed. If also porous, perhaps a little hard wax (such as an automobile wax) is a good thought. Any Lin-Speed Oil that has not dried promptly on such woods can be rubbed away with the fingers or a coarse cloth. Any unsatisfactory dry of Lin-Speed, in less than 24 hours, can be considered affected by some adverse condition, no matter where applied. Most exotic woods dry out in a year or so and can be oiI-finished then, perhaps as part of a periodic maintenance application.
