A customer recently contacted me and stated his delight that I was still in business.
He had purchased a bulk pack of LBT Blue lube about 30 years ago as close as we could figgure after some discussion, and was down to the end of it, greatly dreading the disaster he would be in if he couldn't get more.
That is the oldest report I have about shelf life of our lube, and it dates to our beginning. Interesting thing about the conversation, when I thought on it later, he never mentioned any change in the lube of any kind, so I'm going to presume there was none, and for a fact there was no performance change, which is the critical factor.
For the record, I have never seen a bullet lubed with our lube, with dried out lube. It always looks new as long as it isn't dirtied.
So if you want to make up ammo for storage and be sure of performance many years from now, or if you just want to be sure that you have the highest quality lube available many years from now, you can trust the life of our lube.
