My understanding is that stuff is pretty nasty/toxic. I liked the smell, but probably should have been using it with more ventilation. It was, however, the only thing that could keep my old Springfield XD's from rusting. I don't use it anymore, as I also don't own the XD's anymore.
I've got a couple huge bottles of CLP I'm trying to burn through, but I'll likely turn to less toxic stuff in the future. Mostly using it in AR's until I run out. I've been impressed with Slip2000's products lately, used on my pistols.
