not sure of the amount per litre/pint but i used the smallest ones i could on my z. i just wanted a little bit of flake and only put a little bit in the spray. i think i have about 3 layers of flake spray on her though. (it didn't look right til then) if you are worried about to much flake, it will take more laquer and give you a few more layers but you could try that. but make sure they are light sprays and you let it dry between or it may run on ya then you are SOL
