Thanks guys. This thing sat on CL for a few days before I even saw it. I figured it would be gone, but there was both a Lang 84 Deluxe (older with the bullet nose chamber) and this Lang 36 within 100 miles of each other.
I spent hours next to that cooker last night and it was nice. After I got a pork butt onto the Assassin 28 this morning, I began work on the Lang 36. I kept my word and started with a composite brush, then an 80 grit flap disk. I cleaned up some of the welds and removed some splatter. I also descaled some of the hot rolled steel on it, like the angle iron frame around the shelf to give it a nicer appearance. Lastly I degreased it and applied two coats of BBQ paint. I'd say it looks pretty dang good for about $22 in paint.
I hand cut a piece of scrap expanded metal I had laying around to better use lump with this thing for the time being. Testing that out by running it up to 150-200 degrees just to cure the paint, so that's what I'm doing right now:
