If you are about to invest in equipment, most tanning brands / equipment suppliers will offer some form of training. No point buying someones kit if they are not prepared to get you trained. I've trained hundreds of salons and to be honest, best results from training have come from those that have never sprayed before as there are no bad techniques to overcome. Just be sure you invest in the right kit because if you get it wrong, can put you off for ever. Getting the brand wrong isn't so bad as its easy to change at relatively little cost.
