Hi I was wondering if someone could help me I got my spray tan kit today & it says on the instructions use 50-60ml per tan yet when I've been studying it says you should only use around 30-35ml per tan I have used 110ml on 2 spraytans and couldn't really do 2 coats as it says I should ? Can someone please tell me what I should be using or should I just follow the instructions ? Thank you 😊 xx
