The rusty ram

Dang....you're movin along on it! I believe I'd just rattle can the repairs, and ait till warm weather next spring to paint the whole shebang if that's the plan. It will be too cold to paint before long, unless you have access to a warm shop to do it in.
The plan is to paint the dart next spring it would be good practice to spray the truck first to get some time in and get the gun dialed in.
