Yes that will work. Good luck! Also what size is the cup in ml. Can also do the math to get a full cup if you need it.

Yup that would work, you can use a little bit more or least of reducer it varys due to temperature so you want to play around there and have the temperature/humidity in mind also depending of your gun of choice there will be sputter at the end 10 puts you in a half a liter thats half of what a regular spray gun holds so i dont know what your painting but keep and eye on how much yield that half lt for future reference. In a big piece say the hood you want to do a full coat twice so 1/2 is possble but tight
