Add the drier, close up tight and shake it real good. You must remember to shake the he11 out of it prior to everytime you use it as the drier wants to seperate. They are not kidding...when the Tru-oil is right it will dry in less than 2 hours with a little heat, like sitting near a woodstove. I have finished the hand rub coats and sprayed the final in one day on many stocks. The final spray has to dry overnight. That includes rubbing down with #0000 steel wool between the hand rubbed coats. Wipe down with a degreaser before the spray coat. It also helps to get a perfect finish with the spray if you run hot water over the can to warm it up good before you actually do the spray. Japan drier and a little heat is the key though when you are doing the hand rub coats. You can set it outside in the sun during the summer and get the same effect as the woodstove in the winter. I wouldn't worry too much about trying to rush it along, always better if you take whatever time{within reason} you need. Good luck.
