Do you have to paint over the coverter? Well, you don’t have to, but you can do so to give the application equipment a nice finish. If you used a wire brush to remove rust particles, sand the area to ensure its smooth and free of defects before painting.

It is advisable to sand with 80 grit and 120 grit. By doing so, you make it easier for you to spread the oil-based paint.

What Is a Rust Converter?

This is a water-based primer applied directly onto iron surfaces. Applying rust converter on iron turns the rust into a protective polymeric coating. The coat acts as an fantastic primer for epoxy and oil-based paints.

A rust converter for truck frames contains two active ingredients. They include organic polymer and tannic acid. Tannic acid reacts with rust to form iron tannate, while the organic polymer forms a protective primer layer.

How to Apply the Rust Killer To Convert Rust

First, you must know is that rust converters do not remove rust. They react with it, forming a protective barrier called magnetite. To lay on a rust converter, consider the following.

  • Materials Needed: Before starting, you need the right materials. Try a rust converter in aerosol form. Its application is easy and perfect for both small and large surfaces. You may choose a liquid form when you remove rust converter. If you do so, shop for a reputable brand. Avoid powders to prevent inhaling.
  • Wire brush: A wire brush allows you to remove large rust and scale particles and not to remove all the rust. Why? It defeats the purpose of using a rust converter.
  • Soap and water: Soap and water allow you to clean up the rust converter from the application equipment. Remember, the water should be hot for effective results. There are rust converters that require specialized detergents. Always go for brands that say easy to clean.

Rust Encapsulator vs. Rust Convertor

It’s very easy to confuse between a rust encapsulator and a rust converter. Rust encapsulators can prevent rust from forming or spreading. Apply only on light to medium rust formation.

What you need to know is that it does not change rust into any substance. Rust converters react with rust to form magnetite. Best used on medium to heavy rust formation. On painted or bare metal surfaces, it works poorly.

Wrapping Up

As said earlier, rust on your car parts and frame compromise your safety and that of your passengers. It also compromises the safety of other motorists. To avoid accidents in the future, you must take preventative measures now. Never paint over rust without applying rust converter first.
