I just finished a paintjob were the client asked me to use Dupont Chromallusion... I had not used it before as I am not really a big fan of the stuff... I was suprised at how easy it was to spray!... If you wanted to try something different you could use a couple of different colors combos of the paint... The stuff I used was blue/purple/green you could use two different color combos one for the flames and one for the base color for a different effect... I don't know about your flash question since I have never tried it and have very limited experience with this kind of paint... One thing is for sure you don't want to do too much experimenting at $400 a pint!!!

Here is a photo of the job I did using the Chromallusion Paint...
