Commissario
After trying to paint my Matilda with four paints and a brush I can only agree! The trouble is, I'd want to do it to a high standard and that means investing in too many things.
*shudders*
I don't like to think how much I've spent on the incidentals for our airbrush kit, it's probably more than the original compressor and brush (we're at good bursh number 4, the compressor, extractor, face masks and about a million paints, powders, cleaning products, robo cutter for masking*).
You can get a reasonable starter brush and compressor for about £80, which isn't bad compared to the cost of good traditional brushes.
*Not actually had a chance to use it properly since buying it 18 months ago.
