Well there is a benefit and a downside to it all. Normal BC/CC I shoot filling primers with either the 2.3 or 2.0 mm tips. Base with a 1.5, and clears with a 1.2. I used .015 flake with the 1.2mm tip and it clogs it up rather quickly. Moving up to the 1.5 gave a fair spray, but had some sputtering when the flake would bunch up. It has to be constantly agitated, which is why I used new 3/8" nuts in the cup. BTW, I used Devilbiss DCUPS systems if ya wanted to know. I borrowed a 1.8 tip and it lays it out, but you must adjust the mixture slightly which causes a fair amount of orange peel in the clear. Horrified at first, but the orange effect allows the flake to sit at various angles and really makes it pop. Looking back, I'd put more in the clear, but in the end, I only used about a 1 1/4 cups of flake. After the flake clear coats, 2-3, then I laid down 3 clear without flake, let dry, wet sand, then 2 more coats. Final sand at 1000, and buffed out. Learned a lot, will do it again, but with some adjustment. Next job, the Timi, will shoot flake in binder, then clear over. Flake guns make a mess, but its your call. Hope this helps.
