HOW TO: treat rusted wheel arches.

There may be a build-up of muck around the inner wheel arch lip. Remove any plastic liners and clean it back.

With abrasive, remove all existing coatings.

Remove pitted corrosion with Deox-Gel. This may need repeat application and make sure work is carried out over 10 degrees C as it will be too cold to work otherwise.

Prime the cleaned back steel with Electrox then topcoat to finish. 

It would be worth coating behind the liner with Dynax-S50 wax after the repair is carried out.
