You usually have to spray your hands. The most basic condition is that you have a pen and an air pump. These two things add up to hundreds of thousands (so I can't bear to enter the model after playing 10 for many years)

In addition, you should at least prepare your own hand-painted color scheme, such as Tamiya or Jun's paint.

You said that the electroplating or starlight effect you saw on the Internet should include not only the specific paint (Tamiya starlight series), but also the silver powder used for model spraying, and more than one layer was sprayed. Paint silver first, then spray transparent color+starlight powder. In this way, the material cost of a handmade flower of about 1/8 will not be lower than 100, and novices are likely to damage the handmade flower itself.

It is strongly recommended that you don't do it casually until you have studied it or practiced it with models and other experiments.
