Question about repaints

Hey everybody,
I was wondering how to eliminate brush strokes or simply uneveness in paint applications. The problem seems to be more apparent when I use mat colours, less with the metallics. Should I simply do more coats (I'm kind of lazy and often do just one...sigh, I'm such a newb...)? Is it the brush I'm using? Is it the paint? Or is the airbrush basically the only way to obtain smooth surfaces? Currently, I use Tamiya Colors and decent quality brushes (not sure they're made of camel hair though). If someone could help me out, that would be great.
Thanks.
