I touch a finger into the oil, whether it is Permalyn, True Oil, Tung Oil or Danish Oil W/Tung Oil.
I then dab that finger to an area of the stock, several or 4 times leaving small 'dabs' of oil, then immediately rub it in over the area of stock that much oil covers - like - each side of the butt, 1/2 the forend on each side, then continue repeating until the entire stock is covered with a thin coat. Wait 2 days for the first one to harden, then one coat a day, resisting more often, in order to make sure each coat is hard. No runs - hard finish - perfect.
