Spoke to a paint supplier this afternoon and asked about acrylic lacquer and the first thing he said was "Why would you want to use that, you'd be better using two pack"
When I asked about the requirements for a booth, PPE etc, for two-pack he said, "Nah mate, you just need a carbon-activated respirator, you can spray it outside"
Maybe I'll try another supplier........ 
No pinball cabinets were painted using two pack. As mentioned earlier, it is overkill. If you have primed the cabinet with acrylic primer, then it might react with the two pack. Automotive Acrylics is the way to go.
