I went to the range 2 weeks ago too darn hot to do yard work so I decided to clean the guns. very impressed with the tetra gun cleaner/lube and protectant after months of no use and just everyday carry then over 100 round fired off when the guns were stripped for a cleaning there was still a slick feeling on the barrel and innards of the hand guns which is awesome cause its a dry film no gumminess. I got the can off my dads neighbor that went into an assisted living and had to turn in his guns he had given it to me I think it will last me a very long time I just spray a little on a rag wipe the gun and parts then a mist directly on the barrel and rub in with my finger. It's an awesome product only other lube I use is the pinpoint oiler on the slide rails.
