This was my first time using a product like Rust Kutter. I'd only recently learned that acid could convert rust back to a metal that was paintable. I was skeptical but thought I'd try it. It did exactly what it claimed. I'm way impressed. Note, it doesn't convert galvanized metal rest and seemed to have no effect there. But on the metal roof where I applied it I had solid rust where there was metal where the roof changed pitch and that was nothing but rust. I sprayed the Rust Kutter on and came back a day later and was amazed to see how well it had done actually. I'm a converted skeptic for sure.

I purchased online and never received the product.

It works great for me

Been using Rust Kutter for 2 years now rust has not increased at all on my 02 dodge truck.
