I have been experimenting with producing realistic paint chips with enamels. I only thought it could be done with acrylics but not so. I first airbrush the base coat and let it dry. When completely cured I spray on 2 coats of hair spray. While the hairspray is still wet I sprinkle Coarse kosher salt where I want the paint chips to be. After it has dried and cured I then spray in a top coat and let it also dry. It just becomes a matter of using a soft toothbrush to scrub off the salt. I might need to use a tooth pick for some fine detail work. My 1/35 Sky Raider looks as if it has gone through several campaigns.

Sounds like your having good success,but you don't need hairspray for this technique,a little water works too,just a little,not too much to melt the salt.First sprinkle the water,then the salt,then the topcoat,then just knock and scrape off the salt.Just wanted to share,how bout some pics

I have experimented with using only water with the salt technique but I discovered that when the water dried the salt granules fell off. When I use hairspray, let it get tacky, then sprinkle the coarse, kosher salt on the granules remain where I sprinkled them. It is then an easy matter of airbrushing on a top coat of paint, letting it cure then rub off the salt using a soft toothbrush. Alan
