The wd40 LTCI is a specialized product they now make as a long term corrosion preventative, and not for lubrication purposes. The FrogLube CLP is a cleaner, lubricant and also helps protect against corrosion. And Toney is correct in a previous post, wd40 is really to displace water, it is not a real or good lubricant. I know that there are a few folks that use wd40 on guns and are happy with it. But I don't think they know any better, I would never use it on a gun, unless it was just to flush out water or moisture.
