CAVITY WAX INJECTION

In order to provide greater corrosion resistance, cavity wax injection has been performed for the lower areas of the vehicle,
such as the side member, the side sill and the inside of other panels which have a hollow construction.
When replacing these parts, be sure to apply cavity wax to the appropriate areas of the new parts.
