>>9771239>1.5 is the way to go, 3:1 if you want to waste time spraying 5 light coats for the same results as 1 medium coat.literally the exact opposite in my experience.
thinner paint dries faster and has better coverage (somehow), sprays smoother, gets you much thinner layers than thick paint does.
I should know because I went from 1.5~ to 2.5~ thinner and haven't looked back since.
