I tried using the Sentry Solutions Tuff-Cloth and Tuf-Glide on my Hi-Power and Glock for about three months. The Tuff-Cloth works well as a rust-preventative; but I am kind of skeptical regarding its lubricating qualities.
Part of the problem may be that the PTFE in Breakfree appears to have some affect on the bonding according to another poster who discussed his use of the Sentry Solutions product. I was unwilling to take the leap and use Sentry Solutions products exclusively so I may have unwittingly contributed to the problem. However, not once did Sentry Solutions indicate that such a problem existed in any of their product literature.
During the time that I used the Tuff-Glide and Tuf-cloth my pistols seemed to show higher wear than the normal routine of Breakfree and Tetra-Gun grease on the rails. I also didn't notice any improvement with regards to cleaning.
I still use the product occasionally as a wipe-down cloth for metal items but I have stopped using it for cleaning.
