Looking at the bottom of the tailgate. Reamed out rust with Dremmel tool, welded holes and ground them flat. Now I has solid steel. It's not perfect, but nothing a little filer can't fix.

Still workin'. Tailgate stripped (actually my buddy Greg did the messy part about a month ago). Pounded out some of the dents on the side. Drilled and re-welded spot welds. Rust had started to grow in the top and bottom seams, so I split it opened and sanded out the cancer. Still need to grind some welds and fill some holes.
