01 / IDENTIFY
Identify existing wax, coating or film before washing. Use products permitted for that finish and remove loose dirt before contact.
02 / CARE
Use a dedicated clean wash medium and a compatible shampoo at its labelled dose. Work under the stated conditions, then rinse and dry with clean media.
03 / KEEP SEPARATE
Do not treat washing, polishing and applying protection as the same task. A scratch or etched mark needs assessment before an abrasive process.
The finish is peeling, a mark remains after ordinary cleaning, or the panel was recently repaired.
WORK FROM THE ACTUAL MATERIAL
