Big. You can research what a bunch of people say and go with the consensus, or when you select a supplier, ask them as it relates to the exact product you choose. The latter is your best bet.
I shoot dry flake on clear. I use a Flake King 1000 gun. Mine came from Painthuffer. https://painthuffer.bigcartel.com/product/flake-king-dry-flake-gun-pre-order
I pretty much shoot painthuffer exclusively, but starter off with the ditzler big flake. 95% of the product PH sells I’ve successfully shot through my gravity fed Sata with a 1.4 tip, it gives you a chance to layer it without putting such heavy coats on. Second time I shot the roof on my 65 bird I ordered the flake king dry flake gun to shoot the 2lbs of crushed glass I had purchased. I very rarely go back to wet spraying these days because of how much I like the coverage. I do always use an intercoat clear in my base clear system. Remember that the technical sheets will tell you what the product is recommend for application wise. If it says you 2-3 coats you might be able to push it to 4 but trying to bury the flake can require an extra couple coats. As stated before you need to be able to flat sand the texture out for that glassy finish without burning through the color or removing the flake.
Also! Be careful mixing products or paint types. I see that you’ve got an enamel and a urethane. Some products do not mix and can cause a chemical reaction, which could create checking, cracking, wrinkling or lifting.
measure what you add to the clear or intercoat, I use a tea spoon, heaped, so if I need to do more I know what my ratio was. I add till Im happy with coverage so I can do maybe 3 coats max to get where I need to be, sometimes its one coat, depends on what Im trying to do, write it down on the can of colour your using, you will forget!. If you find the clear too thick , start over, do a practice panel , even cardboard will work, you should add more flake till your happy and switch to an intercoat clear if thats in the budget.
