I am not familiar with the product that you are discussing, but it sounds similar to Boshield T-9, which is superb for tools, guns, etc for long term storage.joshb said:If you're talking about the Shield in a spray can for "long term storage", then yes, I use it. I have some guns in long term storage in plastic gun bags and the Shield works great with them. I check, clean, and re- apply once a year.
