I'm probably late to this party, but when i re-finish gunstocks I generally strip most of the old finish with 60-80 grit (carefully) using an orbital palm sander, then hand sand with like 220, then clean with compressed air and a tack cloth, then a coat of Watco Danish oil finish. Let dry for an hour or two (depends on temperature) then buff with steel wool- 000 I think. then compressed air and tack cloth again, another coat of Watco, light steel wool, air and tack cloth, let dry overnight. Finish with a coat or two of Carnuba wax, looks great!
