I spray tan myself too - it's really weird at first and a bit nerve wracking lol but with a full length mirror and a few adjustments it's really easy once you get the hang of it. I was the same as you, used to working in a salon and having treatments done by colleagues then out on my own and had to rely on myself. Work from your legs up and do your arms last because you'll be bending your arms a lot faffing around with everything else. You might have to use a combination of vertical spray setting and horizontal to get where you need to, lift your legs up, twist your body around, get into any position you can to get to where you need. You will probably have to hold the gun in your left hand and then right hand to get to different places and be prepared to break a lot of the rules of spray tanning lol. Trickiest part is your back, to do mine i bend right over so my head is near my feet, lift my arm high so it reaches over my back and spray from side to side this will cover the top half, to do the bottom - hold gun in your left hand to do the left side of your back, ribs, hip and bust. Do the same on your right side using your right hand. I find it helps by twisting my body in the opposite direction at the same time as moving the gun side to side to get it done quicker and can get further around. Legs - lift your leg up and spray from your feet to hip, turn your leg in to do the outside, then turn it out to do the inside, rest heel on a stable surface like a chair lean over a bit to reach under to do the back of your legs (should be able to cover the buttocks at the same time too). Face, neck, shoulders, chest and abdomen are easy just point the gun at yourself and spray as normal. Arms - lift your arm out straight spray down the centre and make a quarter turn and spray, quarter turn again and spray keep going til you've covered the whole arm then lift your arm up in the air and spray to cover the underneath. Hope that makes sense lol i'm sure you'll work out your own little routine and master it in no time but there's mine to get you started hope it helps a bit.
