However, the skeleton generally does not need to be painted inside, and it is usually sprayed with armor outside.
If you really want to electroplate the skeleton, polish it with water sandpaper, fill the soil, and then apply a layer of starlight silver and 3 to 5 layers of varnish.
If you want other colors, the gray is darker, or even black luster. After the soil is filled with water, it is painted with bright gold (silver is ok, but the dark color is generally gold and the light color is silver), and then the upper layer is transparent and black, and the varnish is 3 to 5 layers.
