Tru-oil story; I make bows and finish them with Tru-oil, I was out shooting my favorite osage bow at my stable of 3D targets that I placed off the deck down I the woods. I set my strung bow down on the rail of my deck and went to check on something, I forgot about the bow.
About dark that evening we got a torrential blowing rain that lasted all night, the bow I left outside never crossed my mind.
At my usual daylight exit from the bed I looked out the door to the deck, there was my strung bow, completely soaked, the leather handle was soaked, I was expecting to find bad things from leaving the bow strung out in the weather for over 12 hours. I got a towel and wiped the huge water drops from the limbs of the bow, there were no water spots.
I unstrung the bow expecting to a find inches of new string follow but the limbs snapped back to the slightly reflexed position that they had held prior to my senior moment brain lapse.
It took a couple of days for the leather handle to dry out but the bow was no worse for the wear.
Tru-oil works for me, I use it on my guns, bows and even my arrows.
