How you set your gun will depend on a few things.
What gun you have.
How fast you move when your spraying.
What solution you use.
Gun settings vary massivley, how fast you move when spraying will also have an effect on how much solution you NEED to be coming out to cover the skin with enough BUT NOT too much solution & what solution you use will also affect how you set your gun as each brand will be slighty different in how runny/thick it is.
You need to clean you gun and then put a little solution in your cup. Get a sheet of couch roll and spray a swipe of solution on to it at you normal speed (best to do this somewhere easy to clean, like in your tent or a shower, incase you get spray anywhere you don't mean to). You want to see colour on the front of the couch roll but it MUST be dry on the back. If it's wet or overly rippled then turn the gun down a bit and spray a new pice of couch roll, keep doing this until you get colour on the front but dry on the back.
When you have done the couch roll test you will be spraying out just enough solution to creat a mist, this will give you a lighter guide colour so you will need to concentrate and ensure you cover all areas of the body until you become used to this lighter guide.
Remember that a darker guide does not make a darker tan so do not be tempted to over spray the client.
Hopefully doing the couch roll test will lower your ml per tan to approx 45/50ml per tan and then from there you can adjust the gun down a teensy bit more every now & again if you feel you can to get the absolute minimum ml per client. (Remember that not applying enough solution will result in a lighter tan though so do not turn your gun down too much :wink2
