Review: Cheap insurance against rust - 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!
Review: Best product we have ever used - Great product. Undercoat the entire bottom of our f250 Ford Great protection for our truck.
