Painting the Tiger 1

Hi everyone,

Just a newbie question: I just bought myself the full option Tiger 1 and was thinking of painting it German Grey. Is it necessary to invest in an airbrush to get decent results? If I stick to spray cans, how do I get the muzzle brake and exhaust effects?

By the way, this forum is a great help an inspiration for me who just got back into the hobby after a 20 year break.

Thanks!
