So what is better Rust Stopper or rust Kutter?
As far as I can tell, the Rust Stopper is simply a rust preventative and not a rust converter. You would want a product that will convert the existing rust into a harmless and protective coating. Rust-Kutter is one of those products.
There are others also. Look for a product that says it is a "Rust
Converter". Personally, I would go for the Rust-Kutter since I know how well it works and it is readily available at any Tractor Supply store. You simply spray it on, let it sit to dry, and then paint right over it. You don't rinse it off or anything.
