Unfortunately there is no layered paintkit available.
There was, however, a "Paintkit" available onece on the cloud9 homepage, if I remember correctly.
When I had the urgend desire to start painting my own F-4F, I sent an e-mail to Dag, one of the very talented
painters at (but not only...) at Cloud9.
He gave me permission to use his layered paintkits, and sent them to me.
There are also a great number of repaints available over at www.sim-outhouse.com
You'll need to be registered, though. Since it is for free, it is a wonderful place to get
any sort of repaint, mostly military, though.
Hope this helps you a bit...
