How to Powder Coat With Multiple Colors
Powder coating allows you to paint surfaces and leave a professional-looking finish. The key is in electrostatically charged particles applied by a powder coating gun. The gun charges powder paint which then clings to the surface being painted. Powder coating several colors can be an unwieldy process but can be done in a similar way as just powder coating one color---with a few different steps.

Tips & Warnings
Check your gun's instructions for more information. There is a chance you may have to adjust the settings in order to powder coat multiple colors.
Be careful when using the powder coating gun. Make sure to cover your eyes and nose when powder coating to avoid any toxic fumes. Make sure not to use the same oven you use for making food for powder coating.
