Set on 3-4 depending which bit I'm tanning, have it lower when doing chest etc as it gets too wet otherwise. Dial at front not too tight and on vertical spray. I go over front and back horizontally afterwards and vertically on legs.
I have mine set on 8 so that means you'd b using more spray than me doesn't it? Because I have found that one spray is too light on clients so I might just keep the 8 setting but do 2 coats? .... Uh I thought I had everything down to a tee and then last nits spray tan error happened...
