Would air brushing the whole of the guitar work and if so what paints should i use?
do you mean airbrushing a design on the guitar?
or .. the whole guitar one colour?
if its just one colour i REALLY suggest using a spraycan
seems easier

the paint sticky will have everything you need for painting with a spraycan
air brushes spray little amounts so would prob take ages, you want a spray gun,

Actually, most 0.5mm Airbrushes, will spray up to about 60mm wide, so you could do a whole guitar, but I wouldn't recommend it either.

Also, if you haven't used an Airbrush before, they can be quite challenging.
