Are you talking about an airbrush system?I've done it a few times. The only advice I can give you would be to treat yourself to one of those hobby air compressors/airgun kits. The cheap ones you get from Lauer with the cans of propellant are cheezy and don't work so well. They extra dollars you spend on the pump system will be well worth it.
You'll get instructions from Lauer, but I recommend to wait at least 3 hours between coats if you don't bake it. Overnight would be better, but impractical due to the pot life of the hardener.
DuraCoat is easy to do, but also very easy to eff up.
Proper prep is really the key. Degrease the hell out of it. Start with brake cleaner, then take that off with Simple Green. Dry it very well before you start spraying. You'll only need one or 2 coats, just be very careful not to apply too much at one time.
As far as degreasing it, I would use denatured alcohol. Every time I use brake cleaner my part sweats. This may be why he recommended Simple Green. I haven't Dura-coated anything, but I have refinished several firearms and the alcohol works great.
Get yourself some latex or nitrile gloves too. Make sure you dont handle the parts with oily hands after they are clean and degreased.
If you wanna bring it all the way to Greenfield I can blast if for you and the Dura-Coat will stick better.

Looks decent enough, but I have to ask, did you take the slide off when you sprayed the thing? The angle of the last pic looks like you taped it (and poorly at that).
