This same thread ran thru the Shotgun message boards 10 yrs ago. I see not much has changed. What I learned then was that tru-oil doesn't keep well, ie once its opened the driers evaporate. The best solution was to use it once and throw it away. problem solved ( in most cases). Others like me who hate to waste things (read cheap here), found ways to fill the bottle back to the top, keeping the air out and driers in. Take most any inert material that will go thru the top of the bottle and add it to the tru-oil to bring the level back up to the top. One guy used marbles, others used nuts, bolts, empty brass shells ... you get the picture. Make sure they are clean. The Japan drier was mentioned but I could never find any, and most places I asked looked at me like I was crazy.

I use the "add stuff to the bottle" method and have no problems with drying in two hrs.
