Still cutting and replacing rusted metal. The drivers door sill had a good bit of rust but it was only about 2” from the the bottom so I just cut and replaced the bottom 2” of the whole thing. I have more fasteners to replace but need a deeper cutting wheel to reach inside of the channels under the floor. I am also wire brushing under each fastener before replacement and coating with rust encapsulator. I also removed the seat floor mount brackets plugged those holes with a dowel rod and wood glue. I will have to use wood filler inside on the floor since these were recessed.
