The bottle I have is the old style black plastic bottle that says "Collector" with "Long Term Storage Protectorant" on it. Hope that helps! Since we live in the desert, I will wipe down a firearm and let it sit wet for about a half hour after the cleaning process then wipe it dry to prevent it from collecting dust. I was told CLP contains Teflon which permeates the metal and creates a layer of protection that doesn't rub off. I don't know if that is true but the CLP has served me well with my duty guns and my current CCW pistol.
