Review on 🔒 1 Gallon Can of Fluid Film: Advanced Rust Inhibitor for Trucks, Snow Blowers, Mowers, Cars, Semis, Tractors, Buses - Prevents Corrosion, Provides Anti-Rust Coating, Undercoating & Underbody Rust Proofing with Superior Corrosion Protection by James Brault

Wow, that thing smells like sheep and it must be made of sheep. Anyway, my wife didn't like the smell when I first sprayed it and complained a bit. On the other hand, I love this business. I used a Graco airless sprayer to coat under my F350 which had a lot of rust on it. It has an odd viscosity: when you stir it, it thins, but once it sits, it thickens. It leaves oil (like mutton butter) on the surface but doesn't come off. Appears to be semi-solid. I probably oversprayed it but it used up about 2/3 gallons on my truck. Definitely think it's worth it. There may be other uses for it like boots and belts and rubbing your hands to waterproof them (maybe Poison Ivy protects them.
