Has anyone ever heard of Fluid Film? I was told about this product last year by my mechanic and started looking into it this year, especially with the new truck. I've read lots of great reviews concerning rust-prevention, and I only dared buy this new "truck of my dreams" because of the reviews. I've spent years grinding, brushing, sanding, treating and painting etc etc etc the frame and suspension (and whatever else I could reach) on my 2004 Xterra. It's fun for me, but has been a monumental PITA, and now I think I'm losing the battle. Now I have this 2015 Titan, immaculate underneath, and I want to keep it that way. Anyone ever use this stuff, or know anyone who does?
