The right sill panel sheet metal is delivered bare or with black storage paint depending on availability and supplier reception. Before final painting, it is essential to treat and prepare it to prevent corrosion from reappearing.

This outer part of the door bottom to be welded is called "adaptable" because it does not come from the manufacturer.
