don't stress fella, not having a go at you at all if thats what your thinking, just trying to help. Reason why i ask is when you have a good, wide fan it helps eliminate spray lines, and if its a low pressure gun, 30 psi could be a good starting base, give or take. Things like this is just trial and error until you get a good flow. Keep up the good work, be good to see it finished!
cheers!
