I just got a line on some free 2" square mild steel tubing that is 1/8" wall thickness. The only issue is its rusty inside and out. I can grind off the outside, no problem. The inside can likely be sandblasted or hit with some acid, or just pour rustoleum in it. I was thinking if the welds were good would it even matter, as there'd be little oxygen left to let it rust much more. Any metal or welding experts have any thoughts?
