When I started this thread - I had a £10 airbrush - since then I've spent hundreds on a professional compressor / airbrush / plotter - the list just goes on and on !
I charge far too little to paint these shells - most take me around a day as I design and custom cut my own masks for each shell on the computer. I paint them as I enjoy it - I'll never make any money from it! And no - I don't charge £10 - but it's not much more
