The rusty area that we found yesterday was wire wheeled and the bad area was identified. The area to be cut out was marked in yellow paint. There is a little bit of rust extending out of this area, but it is for the post part surface rust. The remaining metal is plenty thick for securing to.

Here the bad metal was completely cut out. A 1/2″ thick border was left to secure to.

A 16 gauge patch panel was cut out to fit over the area.

The panel was tack welded into place and then a bead was put around the whole patch.

Next step will be to seal the underside with seam sealer and paint. After that.. we start prepping for the herculiner!
