What is a Rust Converter?

A rust converter is a chemical product that penetrates rust, bonds with it, and forms a new compound. The new compound is normally black in color and water-resistant. It not only gets rid of the present rust but also protects the metal item against future rusting.

The compound also helps the metal item retain its shape and makes it appear younger and stronger.

Prep The Surface

Some people don’t find this step necessary. However, by preparing the surface properly, you will help the product work more efficiently.

Use a brush or roller to apply the rust converter. Applying it on big surfaces is more easily done using a roller. Remember, very thin rust converters need to be sprayed rather than painted.

The product will take around 20 minutes to dry but it can take a day or more to cure.

Apply a second coating to ensure great rust conversion.


Clean Up

The bottle should have some safety precautions; make sure that you read them. This particularly helps to protect you from the chemicals in the product.

Use water and soap to clean the product from the equipment you were using to apply the rust converter.

  • Apply it when the temperature is over 50 °F.
  • Don’t put used rust converter back into the bottle.
  • Use only oil-based paint for the top coating; don’t use latex paints.
