RE: K & B Painta
Check the KlassKote website, if you haven't already. They have all the standard colors shown, and any can be done with gloss or satin. I used the satin catalyst on my Tiger Moth for both color and clear, and it's very nice. On the website, it does talk about mixing custom colors, and there's a reference to a Dave Platt video. That's all I know. You might want to try to call or email. Hopefully they would be as helpful as they were in person at Toledo. BTW, I also have had good experience with their on-line ordering and shipping. Service is quick, and packaged well.
