Choose 1, this car model is a very precious souvenir, and you hope it will remain unchanged for ten thousand years, so it is best to put desiccant and camphor in the car to prevent moisture and insects, and then carefully put it in a self-sealed plastic bag, and then put it in a stable place with constant temperature and humidity as far as possible, and ventilate regularly, otherwise the evaporation of desiccant and camphor in the car may cause fog on the window that is difficult to clean in a long-term sealed environment (which is also the practice of many overseas museums).
Option two, you should always appreciate this car model, play with it or communicate with your peers. So the method of maintenance is similar to that of camera maintenance. Nothing more than dust removal as much as possible. My personal experience is that it is very powerful and easy to buy a bottle of liquid nitrogen for 30 yuan, but every time it is a kind of wear and tear on the door, wheel and steering system (unless it doesn't move), and the light is also harmful to the car paint. After a few years, the paint will dim anyway.
