I had to add some bullet holes to a visor so I turned the camera on so you can see one way of airbrushing bullet holes. You can find a written how to version of this on howtoairbrush.com. Feel free to print it off from that web site if you like.
Supplies used: House of Kolor base coat colors white, black , orion silver, hobby knife,transfer paper,masking tape.
Very easy to airbrush bullet holes if you've practiced your basis's you should have no problem airbrushing these.
