Just clarify those first two pics are of the cargo area floor, third and forth pics show the pax side and my then shiny new cat. Fifth pic shows the pax floor pan after hours of grinding, acid treatment and a coat of rustcheck "coat and protect" painted on. The sixth pic shows the completed repair, the floor was segmented back together to reduce the "oil canning" effect, each segment was treated with rustcheck as well (after a good couple coats of tremclad). Since those pics were taken I had my neighbour mig weld the edges.
