- Remove oil, grease, paint and loose scale.
- Apply Ranex & allow to dry completely in order to penetrate deep rust & to leave surface in a suitable condition for painting with an oil based primer, as Ranex chemically destroys rust it is not necessary to use rust inhibiting paints. Zinc rich paints are not recommended.
- Apply Ranex to the rust effected areas only, wipe off any excess on surrounding metal or paintwork with a damp cloth.
Note: Ranex Rustbuster will convert the rust however it will not prevent it from re-occuring. Treated surfaces left uncoated may experience further rusting.
