Hi there. I'm about to book a course with Novoutan hopefully and I wondered if anyone can help me. Can I use any tan solution in any gun? A friend of mine used to be the face of Fake Bake therefore has brand new guns, tents etc that I can have for a very good price. I don't want to use FB tho after reading so many polls on here. So, can I put Novoutan or Sienna X etc in a Fake Bake gun? Sorry if this seems like a silly question!!
