Using the new clear gloss powder coat I just got I mixed a bit of Emberglow color shift pigment to about 1/4 ounce of the clear. I painted a few jigs black then ran a couple thru the Emberglow concoction and this is what I got.

The Emberglow shifts from green to gold to red and can be seen in all three colors here in this picture. Its a little grainier than the airbrush can handle but in the clear as a top coat over black its just something else.
I did learn that just one quick whiff thru the clear is all one needs to do....no double swirling here or you load the detail of the heads.
My plan is to make the 1/4 ounce batches of clear with every color shift I have and simply store these as the clear product arrived....in zip locks. Just pour into a cup for painting, then back in the bag. I'll write color shift name on each respective bag for quick acquisition.
This Emberglow was donated to me and I've been threatening to do something with it and its found its niche now. Really, really pretty stuff on black.
