Yeah, as people have said really, sand down between some coats and make sure you get as smooth a surface as possible to spray on, and to laquer on. 
The way I get a nice shine on things I spray is to put two coats of laquer on, about 20 mins apart or so, let that dry, sand it back with 800 thne dust a coat of laquer over again, then polish it up when its dry. Brings it up to a lovely shine. Everyone has different ways of doing things, but that works for me.
