Product Information


FE123 is a modern formula rust converter, safe to use with fantastic results.

Please see the test panel below, on the right-hand side is showing signs of surface rust after having the loose material scrapped and wire brushed away form the surface. Once a thin coat of FE123 has been applied you can see on the left that the tannic acid in the FE123 has reacted with the surface oxides and converted these to a stable ready to paint surface.

FE-123 envelopes rust at a molecular level, developing into a neutral layer which exists between the steel's surface and the atmosphere. This neutral layer prevents the migration of ions so that no chemical reaction can occur at the metal's surface. Recent independent testing by 'PRACTICAL CLASSICS' magazine April 2011 proved that FE-123 not only converted the rust but also left a foundation that could be painted over without neutralising and came BEST IN TEST scoring ten out of a possible ten points. If you would like a copy of the report, you can down load from the top of this page. We were also awarded best in test by CLASSICS MONTHLY in there 2011 long term test results.



Product description

White in colour surface rust converter, once conversion has taken place FE123 will turn to a purple grey colour.

Direction of use

Pour a small amount of FE123 into a separate container so not to allow contamination. Apply FE123 sparingly by brush directly to surface rust working into the metal. Allow the product around 15-60 minutes to convert (time taken will depend on the temperature) once converted you can paint/wax straight over.

Once converted FE123 will turn Purple Grey if this doesn’t happen there may not have been enough oxides present for the conversion to happen, alternatively it could also be to cold.


Brushes and containers can be washed out in fresh water


Wear suitable protective clothing, gloves and eye protection
