This weekend I have started to build Tamiya's M151A2. So far the fit is almost flawless and looks like a promising kit. I got to a point where I'm stuck. I have to assemble the wheels but they also need to be painted. My question is when do I have to paint the wheels, after glueing them on the chassis, or before. If the painting occurs after, then how do you mask them. I am a newbie to painting so I'll need all the help and advice you can give me. Thanks in advance.
