As with anything in life, do enough of something and eventually it will go wrong. While I was priming the Sherman, my compressor died. It's only a cheap one and lasted 3 years but couldn't have happened at a worse time. I finished priming with a rattle can instead, going for white as the paint in photographs of said tank is very faded and this will make the faded paint effect easier. If anyone knows someone with a second hand airbrush compressor going, please let me know. I'm not rich (given an upcoming wedding) but I've some cash to spare!
