CLP is CLP22, produced by Sentinel Canada based in Montreal. They are a manufacturer of Lubricants and chemicals.
I like it for use on just about everything metal. I used it to free up sticky door latches and lubricate hinges. I also use it to wipe down my rifles before I store them. It has the lubricating properties of an oil, with the penetration properties of liquid wrench or WD-40.

Here is thier pitch for SENT CLP.
SENT CLP (Cleaner, Lubricant and Preservative)
For Weapons and Weapons systems
SENT CLP is a highly penetrating, mobile liquid lubricant which combines three essential functions in a single product: Cleaning, Lubrication and Preservation of handheld weapons, and weapons systems of both large and small caliber.
SENT CLP provides additives which in addition to their ability to penetrate between metal surfaces, aids in the effective removal of built up dirt, corrosion particles and firing residues which can be abrasive to both recoil and gas operated mechanisms.
After cleaning, a thin-film layer of preservative forms immediately on the surface which not only displaces water but provides a corrosion resistant barrier against rust and dirt.
