Hi, I have recently purchased the HLVP maximist xl machine hoping to do mobile spray tanning. I am not qualified yet though have been shown by an experienced friend. Practised on two friends whilst she guided me and tans turned out fine. Though yesterday I tried to do it alone on another friend and found that whilst spraying her, the solution was dripping terribly down her skin, why could this be? I have 4 clients next week and have only two more trials arranged for this week so I need to perfect it, any help plz???
