That is lookin good!

When it gets time to paint, or coat it in something. I can't recommend enough something like "Rust Bullet"- Amazon, or Miracle Paint(Ebay, or Bill Hirsch). It drys because of moisture, so even on a wet day. Hardens like shiny smooth concrete. Yet somehow not brittle.. Way better than cheap black paint.. Both work amazingly well. The combo of one of these epoxy paints, a welder, and some fiber glass means you can do almost anything..

Needless to say use a respirator.
