@bkrantz - I made it back from Dallas so, I'll fill you in here on the SEM.
You can buy the gun here:

As far as factory look goes, we got close. We played with it for a long while, more air, less air, closer to the metal, further away from the metal, etc... until we found a combination that we liked. It's not perfect but, its good. Had we tested more, there's no doubt in my mind that we could have duplicated it almost exactly.
Here's some pictures for you, after the car was painted.
