Jim,
yes, just like the dodge pickup
Doc,
I do not have any video tutorials at this time. But I do have a few things in the works.
I watched the video of the spoon test. If I may make a suggestion...don't trail off with the airbrush on every flame lick. What I mean is, just spray a small section of the stecil and let that be it. I realize that the spoon test was only step 1, Just a simple suggestion.
You may want to order a set of the mike levallee true fire stencils in the nano size, if you haven't already.
here's a picture of a hood that a friend of mine and I did when I was 1st trying out the process. I'm not 100% happy with it...but i am hardly ever 100% happy.

here's a few more to possibly help (not green fire)...


Now, I'm not a pro at this and I learn a little more each time I do this technique.
You might want to get yourself some reference photos of fire. It sounds silly, but it does help.
Be sure to go sparringly on your "highlight" color. And don't stress it too much...it is only paint and can be fixed.
I hope this helps you out some and didn't confuse you even more.
