This is a great product, now that it is summertime and we use a swamp cooler to cool our home that places a lot of moisture in the home and that is not good for any of our fire arms.  Moisture is bad for any of your fire arms. This is a great and inexpensive way to keep them looking new.  Rust is one of the worst thing you can have on your gun old or new. This is a must have product.
