melt any amount of bees wax in an old clean coffee can
mark the level of melted wax inside the can
pour the melted wax into another container that will hold four times the melted wax
pour turpentine into the original can up to your mark
add the turp to the wax
pour boiled linseed oil into the original can up to the mark
add the linseed oil to the turp/wax mixture
mix it all up well, then set it aside. at 70 degrees the mix will be about the consistancy of bearing grease. Put a dab of it in your hand, and work it into the stock. You may start/stop as often as you need to, and it will make no difference. The friction from your hand will allow the wax to penetrate into any openings in the grain or finish. After rubbing, let the stock sit for an hour or two, then buff it with a terrycloth towel. On a gloss finish stock, you won't notice much difference in appearance. On other stocks, you'll end up with a satin finish, and any stock treated will be impervious to water. This mix will not build up, and will not leave the stock "slippery".
I mixed up a batch six years ago, that almost filled a 40 oz peanut butter jar, and it took 1 pound of bees wax (and appropriate amounts of oil, and turp). I do 8-10 stocks a year and still have over half a jar left.
