The second door is my problem child as it's in a borderline condition where I think it can be saved. I just don't know how to go about it. I initially hit it with a wire wheel which didn't do much so I went at it with a flapper disc. This brought out the pits but overall it's not too bad (I think). My question is what should I do now? Continue grinding and risk blowing through the metal? Hit it with acid, paint, and hope for the best? Or is there another tactic?
