Optional: Ceramic Pro 9H Permanent Bond Nanoceramic Protective Coating - 2 layers are pre-applied before shipping
Ceramic Pro 9H forms a permanent bond with the surface and will not wash off or break down. It is a highly durable protective coating that protects your vehicle's paintwork or any other surface from damaging contaminants. The unique formula of Ceramic Pro 9H allows it to be applied in multiple layers which means the thickness of the coating can be increased with additional layers, allowing a thicker/harder coating with improved scratch resistance.
