Two-Toning and Multiple Coats in Powder Coating

With all the Eastwood HotCoat powders, you can apply the first color, cure it, let it cool, mask it with high-temp powder-coating tape and use aluminum foil as masking material.

Ensuring a good ground (that is a critical point in multiple coats), apply the second color, then put the whole project in the oven again for curing. When done, carefully pull the tape and foil away.

There are two types of high-temp powder-coating tape: Fiberglass Masking Tape in 1/2" and 1" widths, and the Blue Mylar High-Temp Masking Tape.

Eastwood’s Dual-Voltage HotCoat Powder Coating Gun is particularly good at applying multiple coats of powder.

As an alternative, or as you become more familiar with the process, you may want to pre-heat the part to curing temperature (after adding the masking tape and foil, of course), pull the part from the oven, apply the second color and place it back in the oven for a final cure. This avoids any issues with assuring a good ground. This technique would of course become a necessity if doing a tri-color scheme.
