Maybe Joe is right; I am a tinplate abuser.
Everything was going great until assembly. I thought it would be best to assemble the shell before masking and painting the ends of the yellow sides. Wrong. Also, my yellow paint was not hard enough, and I damaged a spot on the side trying to put the doors on. When I masked the yellow, the tape ruined my finish, then the clay colored paint wrinkled the yellow. I mounted the shell too soon on the frame and could not get the door hangers tight. Now my doors are loose! I would strip it and start over, but I'm afraid I will break tabs. I am half tempted to sell this one as is and start over. These refrigerator cars are a bit of a pain.
At least the roof looks good!
