Yesterday while I was shooting, I laid two rifles in the back of my truck. In the truck there is a black plastic bed liner. The temp was around 70. The rifles had been laying in the sun for about a half an hour and when I picked my 91/30 it was absolutely drenched with a liquid (cosmoline?) there was literally a puddle under the rifles. I have spent countless hours cleaning cosmoline off of these rifles and I have no idea where more could have come from. It appeared to be sweating from the stocks and oozing from out of all of the cracks and crevices. Have you guys noticed this?
