A rust converter is the common description term usually given to chemical products that when applied to an iron or iron alloy surface, start a chemical process to convert rust. During the conversion process the rust converter changes (iron oxides) into a stable organic iron complex. This process usually provides a visible black layer that is resistant to moisture whilst protecting the surface from future corrosion.
Why a rust converter is ideal for classic car restoration.
Commonly called a rust remover or rust killer product the rust converter application process is ideal for items or surfaces that prove difficult for sand blasting including sheet metal, fences, farm equipment, iron railings and vehicles. If you are looking to preserve a classic car vehicle with important historical heritage, we recommend treating any evident rust during maintenance or restoration with a suitable rust converter.
Water based Rust converter
With water based rust converters they usually contain two ingredients an organic polymer and tannic acid. When the tannic acid comes into contact with rust, a chemical reaction takes place and the iron oxide commonly known as rust is converted into a dark coloured blackish material ‘iron tannate’. With the 2nd ingredient the organic polymer ‘2-butoxyethanol’ this finally provides a protective primer layer. Unlike rust removers, rust converters form a chemical reaction once applied to rust leaving a black surface that can be painted over whilst preventing further surface corrosion to occur.
Rust converter application treatment preparation
Before applying a rust converter it’s important the surface is prepared and cleaned by removing any rust with a wire brush, sandpaper and hammer to clean up the treatment area. Usually rust converters can be applied with a brush, roller or via conveniently spraying with an aerosol. Once applied the rust converter treatment application will adhere to painted or non-rusting surfaces, but will not provide any additional protection or benefits on these sections. Whilst it’s not essential, if the treated surface is exposed to the weather including rain, salt, snow or mist or general outdoor conditions it’s usually advisable to paint over the rust converter treated area for added protection. If you are looking to provide a vehicle with a complete rustproofing treatment, our DINITROL RC900 rust converter is supplied in many of the D.I.Y. rustproofing application kits we supply that are very popular with classic car enthusiasts and people who work on vehicle restoration projects.
DINITROL RC900 Rust Converter Product
Once applied this product supplied in a convenient aerosol for easy application converts rust into a stable organic iron complex, whilst providing a protective barrier layer against further corrosion occurring. The specialist rust converter is highly penetrating compared to other products and contains a complex organic chelat base and epoxy solution. You must keep applying the treatment until you notice the surface area becoming blackish in colour that is then suitable for paintwork or other corrosion protection products to be applied. However before applying any additional coatings make sure the DINITROL RC900 rust converter is completely dry with no moisture present and a strong dry impermeable barrier has been formed. Sometimes when a lot of rust is evident you will need to keep repeating the treatment application to the affected area before the surface turns to the blackish colour signifying that the rust has been converted.
DINITROL RC800 Rust Converter Product
Once applied usually with a brush or roller the co-polymer latex and organic agents convert the rust on corroded ferrous substrates into a stable organic iron complex. Once dry the polymer based DINITROL RC800 product that does not contain lead or phosphoric acid, seals out any further corrosion by forming a barrier against moisture and oxygen. Rust is caused due to the chemical reaction when iron or an alloy that contains iron like steel for example is exposed to moisture and oxygen, an oxide is formed weakening the substrate.

DINITROL rust converters are ideal for classic car preventative corrosion protection treatments and during restoration projects. Before applying vehicle cavity waxes or underbody chassis coatings if rust is evident we recommend treating the affected area with a suitable rust converter product.
