Personally, I started "cutting" my colored powder's with high gloss clear to stretch them since I started out with nothing but 2oz jars & I had no idea how far 2oz of powder paint would go. Then I realized that by adding the clear, my colors actually have more depth & colors like Matte Black become Gloss Black and any other color that was a low gloss, becomes a much shinier color. Now I routinely cut my new powders and I'm able to share powder's with other jig painter's.
