My comments related to two topics. The easy one is the front bumper conversion. Not sure if this is a current photo or not, but it looks as if the large, gaping holes from the later bumper supports have not been patched/welded to result in thin slots for your new (old) bumper brackets. The other comment is harder to describe. But I would assume that the car will be fully primed (after several iterations of blocking and sanding). What I suspect they would ask you to sign off on is the fairness of the resulting surface that they are about to paint. Sorry, that is a boat building term, but that is all I know for this. The pics above seem to show some spot patching, but there is not yet evidence of those patched areas being faired into the rest of the metal work. Hard to tell from photos, though...
