Hi – I‘ve bought a 3dr Range Rover Classic from JS Scale and my plan is to make it look like properly unloved and knackered. I’ve done a few classic Tamiya SRBs and weathered them using brushes and a variety of other stuff but I’ve never used an airbrush. Not sure where to start, or even to bother. I love fine weathering/ageing detail and the accurate scale look is very important. I’d welcome any thoughts on where to start with an airbrush setup. Thanks in advance.
