Hi just a quick one.. the heading says it all, i have the fake bake machine.. the one that resembles a pig lol and there are measurements on the cup the tan goes into.. i was wondering how much tan i should be using on average per person.. as i feel i am using too much.. i turn my gun to a setting that ensures a fine mist when spraying on the skin.. but clients always say they dont think its dark enough etc so i end up spraying them another time? any advice? x thanks xx
