DE.OX.IT is ready to use, however may be diluted 2-3 parts of water to 1 part of DE.OX.IT if required.
Working on small areas at a time, apply onto bare metal areas with an abrasive pad. Before DE.OX.IT dries, wipe off with a wet cloth and dry thoroughly with a clean cloth. If DE.OX.IT comes into contact with old repairs ( e.g. bodyfiller) and painted surfaces neutralise the area with water immediately.
Allow 15-20 minutes to activate then wipe down entire surface with methylated spirits and prime within 30 minutes. Clean up residue with water. Surface must be completely dry before painting. Paint as soon as possible.
