Right heres the problem. i reckon i'm using 100ml per tan. I was trained to do 2 coats. I'm doing it all over twice (in full both times). My gun is set at 8 o'clock (perhaps i should change this?) but i think i defo need to look at my technique. I hold the gun approx 30cm away. I also have my front dial set at about 8 o'clock and use circular motions on legs & arms and go across the torso & back. I'm not sure i've got much faith in my teacher so would any of you lovely peeps please let me know your technique/routine please???
