This is the gravity gun i use and its fantastic for the money, there is two different types depending on how powerful your compressor is. I use a 250l direct drive 3 phase.

fit moisture trap if you haven't already otherwise you'll get water beads form and you gun will splutter and ruin what you doing, Plus it will make your lacquer go cloudy.
The most important part of it all is the prep work. If it's not right it the end result will look pants and not last and i agree with what has been said, give it a go is the only way to learn. Don't rush or put on heavy coats.
I've done spraying through work so i didn't pay for all my balls up's
