I do some small job powder coating for personal use and I have used Prismatic powders fairly exclusively...I have never had a huge difference in a sample chip and the powder.

The problem with coating a different color (over current color) to the part is twofold in my untrained opinion...

1. The underlying color will make the new topcoat color a different shade, even slightly...that is how you can get some different shades and effects.

2. The only time I have used a color over a color, usually when I use clear powder for clear coat...or when I do a candy color with silver flake as the first coat...the 2nd or 3rd color doesn't want to adhere to the first color as well...I usually use something call hot flocking where the part is heated and then powder coated...so it sticks to the hot part and melts immediately, but then still needs to be cured in an oven.

I would ask the shop did they do anything to the part before powder coating it...just to make sure they didn't put another color under it for some reason which could change the shade.

Unfortunately if it were me, I would want to strip it and start over with a different powder coater...or ask them to see the powder they used...it should have the prismatic # and color name on the bag or bottle the powder is stored in.

Sorry this happened to you! Good luck.
