I use fluid film quite a bit as well mostly for undercoating my vehicles for the winter. It does work well. One thing about it is that when you use the sprayer attachment they have you have to run it at about 80 psi it order to get the siphon strong enough to suck that stuff up.
Works great as an overall lubricant but for a penetrating oil for breaking loose rusted bolts I haven't anything better than PB blaster.
PB Blaster is a joke compared to Kroil. Seek some out and you'll see the truth. I'm an FF fan also but I dislike how dirt sticks to it and it doesn't last long enough to be an good underbody spray. But if you have time to reapply frequently it's cost effective.
