Short sumary: don't waste your money on that. for 50$ you can get a WAY better airbrush (Badger or Paasche, even Iwata for a bit more)
The Air can that come with that kit didn't even last long enught for one kit. it's very expensive over time (more than a compressior) Also the airbrush included don't acept Enamel or Lacquer Paint, only Acrylic. If you put any other paint, the nozzle will melt and you will need to buy a new airbrush (I know, I got this kit first, then got a Badger Anthem)
This is a major downside when you can't use 80% of the paints.
all your question will be answered in the other thread. btw this thread is only on the second page, and it's one of the biguest lately.. you didn't search very hard
