Thanks JWC. I got the 30118 field drab and 34079 forest green from RAPCO, but didn't like the forest green at all (way too dark). I understand these are Alkyd enamel paints.
As luck would have it, after some research I stumbled across a very happy finding. PPG (an automotive paint) has the 34094 color already programed in for an acrylic enamel. They even have notes on what proportions of hardener (DXR80) and flattening agent (DX685) to add to get it just right. I had some of this mixed up in spray cans and it cost ranging from $11 a can to $12.95 depending on where I went.
One down side to spraying from cans: You can only hold roughly 5 oz in a can and by the time you add all the flattener, there's only enough room for about 3 oz of paint. The rest is flattener, and it does tend to thin the paint out. Also you can't put any of the hardener in the cans so you'll never get as durable a finish as if you mixed it up and sprayed it from a gun.
Oh, by the way, if any of you are interested, the PPG paint for 34094 green is DAR46260 (I believe the DAR stands for Ditzler Acrylic Resin) As I mentioned, The formula includes mixing proportions for paint, flattener and hardener. Though it might be more expensive, this may actually be a better paint to use than the Alkyd enamels since it is an acrylic enamel. I think I recall the guy at the paint store saying that it is available in a polyurethane too, which is an even better paint.
I have a hunch that if the 34094 is in the PPG paint data base, some of the other colors may be too, however I haven't verified this yet. This would be really cool if so, since it would mean I could virtually have a local paint source just about anywhere I go, all I'd have to do is find a PPG dealer, and know the paint codes and I'm set.
Another benefit to the PPG paint is that they come in an "OMNI-PAK" spray can that has a much better spray tip than your typical spray can and it it applies the paint much more consistently. I don't mean to criticize RAPCO, I love the field drab I got from them, but the spray tips on the cans aren't real great. They cause the paint to sputter and drip, and I got large drops of paints sputtered onto the surface I was painting.
