Bare metal surfaces of car body shells are protected by a conversion layer in the form of a phosphate coating applied in the OEM paint shop and protected by an e-coat layer. A damaged coating can cause corrosion and must be rebuilt.
During repair activities such as sanding, cutting or welding, the protection coating may be partially removed or destroyed. It needs to be rebuilt to reinstate the original level of protection.
