How to Create A Patina Look

First, spray your main color of choice; let’s say it’s blue. Then you spray a patina-like color such as brown where you think a body would be rusted in real life. Let it fully dry. Next, apply salt to the body and follow it up by spraying the first color again (in this case, blue) over the salt. Allow to fully dry. Once it’s dry, remove the salt. The effect you get is a rust look. It can take some practice to get it down just right. If you need more guidance, look up videos online, they’re pretty helpful.
