Inferior, well yes. I have FL, sitting in a box now. I found I had to reapply it too often. But, Inferior doesn't say how much.
I believe it works if you follow directions, but I'm surprised how many people don't. Watching videos online it is evident that they don't, that's where some part of there are better products come in, for the populous.
I still believe that other products are better, like slip2000. But I do like FL for coating parts like I would a silicon cloth, keeps from moisture etc, and not oily. But my friction parts have slip2000, and I hate using two things and having to heat something to apply it.
I still believe FL works well, but after switching to slip, I'm not slipping back lol.
