I stumbled upon an older forum while googling for an airbrush feature for Paint net.   http://forums.getpaint.net/index.php?/topic/8928-air-brush-and-spray-paint-effects/   granted it is old but I still am interested and want to know if this airbrush plugin from usedHonda is available and if so where?    Will the Paint net 4 would have this airbrush feature incorporated?   Thanks
