Todd,
First off read the HOK tech manual, come back read it again.
Clear is a 4:1:1 ratio. 4 parts clear, 1 part reducer, 1 part catalyst. Buy your catalyst and reducer in the pint containers if you wont use it all quickly they store better unopened.
I use about 3 ounces mixed per clear session, giving me about 3 flowing coats for a body.
My recomendation would be 2 sessions of clear, level sand then flow coat. Buff and polish as neccesary, but a lot less this way.
For a kandy, I would consider the Kandy base coats, very close in effect much easier to spray.
Are you looking to show wood grain? If so I would clear it, level sand, rescuff with a red scotch brite then kandy it.
If your looking for a solid color, you should use their primer and sealer. Yes you can mix brands and yes paint jobs can blow up, seriously HOK is formulated for custom jobs and a much great mil thickness than production paint. Skimping on the primer is like saying build my house with a styrofoam foundation the foundation doesn't matter. Their primer requires a sealer to paint over, also catalyzed, the good news is the sealer is tintable and the metallic sealer is great. For a kandy job I would go over the metalic sealer, either silver or tinted with 5% pagan gold depending on the top color.
For cleaning the gun I use gun cleaner, you find it at Home Depot labeled Lacquer Thinner. Reducer will work but is way more expensive.
The great thing about Coast is if you call them and ask questions they know what they're talking about, more so than I do.
