I've used CLP forever, but on another forum, it was brought up that if you had to shake a lubricant before using it, it may not be the best choice. The reason, presented, that if the teflon separated in the bottle, it would do so after application to the gun. The argument makes sense to me and since I have many other highly regarded lubricant choices, I now use my CLP for hand tools and such. In my small collection of lubricants, I wouldn't run out for about 100 years and I'm sure I'm not alone.
