Using this Walthers vintage grocery store kit is a breeze. First, carefully unpack all the parts from the box. Lay them out on a clean surface so you can see what you have. Start assembling the walls with the cinder block and brick details. Attach the large pane windows and the 'glass' entry/exit doors. Place the decorative front planter box in front of the store. For the back, put together the loading dock with the overhead door and the'steel' employee entrance doors. Add the large signs to the front and sidewalls, and don't forget to mount the sign on the roof along with the two air conditioners and the large vent. Attach the electrical box, gas meter, and downspouts to the appropriate places. Then, connect the detailed base with the sidewalks to the main structure. As for parking lots, you can buy them separately and place them around the store as you like. When it comes to maintenance, keep the model away from direct sunlight to prevent the colors from fading. If it gets dusty, use a soft brush to gently clean the parts. Avoid using harsh chemicals as they may damage the plastic. With proper care, this vintage grocery store will be a great addition to your model train layout for a long time.
