Fluid Film Undercoating Protection, Rust Inhibitor and Prevention, Anti Corrosion Multi Purpose Penetrant and Lubricant Lanolin Formula, 1 Gallon Black Color

My buddy and I have found this product to be a great addition to helping keep our trucks in great shape. It help keep all the road salt & brine off the undercarriage of our trucks. It can be tricky to apply the first few times until you the hang of it. It does have a weird smell to it but it goes away with a few days.

I’ve been using fluid film for about 6-8 years now. I undercoat my truck every other winter. Fluid Film is better than undercoating and easy to apply. It won’t harden like undercoating so it doesn’t trap in moisture. It will wash off but on in the wheel well areas. Under the truck and along the frame it stays on for years. One gallon is more than enough to coat my truck. The only con with FF is it smells like manure. That will last a week to 10 days. It’s worth it to save your vehicle from rust!

I put this on my truck 4 years ago ago when I bought it and it works great as a protectent

Works amazing

Great product. Undercoat the entire bottom of our f250 Ford Great protection for our truck.

Great product for black metal parts. The clear is great for all parts. Leaves a oily coating makes cleaning 4x4 mudding toys easier.

Great product, highly recommend you purchase the spray gun and 360 nozzle for ease of application.

Use to use the original fluid film but tried the black, works just as good and love the black. A must to fight the rust

Great stuff I put it on with a brush

Good stuff

Will buy again

Very good product, sprays on nice and thick, we will see what it looks like after winter

Good stuff
