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

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

Worked fantastic on my truck with the fluid film spray gun. Worth the money. Will purchase again.

This is a fantastic price for this stuff, especially in black. I used one gallon to spray the frame of my 1996 k1500 6.5 foot bed extended cab. My particular spray gun was spraying a little too heavy so you could probably get away with using less than I did with a better setup. Get yourself some rust protection and make your rig look a little nicer!

Works amazing

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

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

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.

Nothing better than fluid film I spray my truck with this product love it.

I bought this again to recoat my 98 Ranger after being happy with last year's results . Once I crawled under my truck it will only need a couple touch ups because it's still holding up well.

Fluid film is top quality as always, just a little bit less expensive on Amazon

It work so well

Used this on my rocker panel after it was repaired. My only surprise I had, was that it was thick. I had assumed it would be like the clear Fluid Film that is in the spray cans. Nope. Still did the job.
