Frequently Asked Questions (FAQs)

1. What is better rust remover or rust converter?

BEST USE: If you're looking to resurface metal and require that the end result be exposed rust-free bare metal, then a rust remover is better suited for the task. Think rusty screw driver or the inside of a gasoline tank... items that you would NOT want to coat with paint but rather restore to a pure metal state.

2. Can rust converter remove rust?

Rust converter is an easy and safe alternative to physically removing rust from a corroded surface. Using rust converter needs no special experience or equipment and is highly effective at protecting a surface and preventing further damage.

3. Do rust converters work?

Nevertheless, rust converters are effective solutions for most of these rust problems. If you are wondering how rust converters work, it will help to know that the iron oxide forms with the contact of metal and moisture. Thus, the rust converter works on turning the rusty metal surface into a non-rust form.

4. When should you not use a rust converter?

We do not recommend using Rust Converters inside water tanks. This includes other tanks that contain liquids such as petrol. You do however use rust converters on the outside of these tanks prior to a coat of paint.
