Hi just started doing spray tanning after training and buying a full set up with tantrick and having problem with the 12% solution. The tan looks lovely for a couple of days but then it goes all patchy and speckled around the neck and chest area? really bad looks awful like someone sprayed over top of tan with bleach! I have done 3 people with this and followed routine to a t, also gun is set on very fine so not soaking. Any help please as cant carry on using it. Also made sure they all exfoliated thoroughly and moisturised night before.
