I have no use for FL and also think CLP is over priced. For the last ten years I have been using synthetic motor oil (various viscosities for different uses) and it performs just as well as CLP for a fraction of the cost. I haven't tried FL because I know a rip off when I see one.
What amazes me is the people who use CLP to clean a gun. Oil simply does not clean as well as a solvent and costs a lot more. I use Brake Parts Cleaner for all of my cleaning, except the bore where expensive cleaners are necessary. And save a lot of $ in the process.
