I've been wanting to do some of these S-Model kits I have around and wondered if you guys had and tricks for painting concentric tires on the "all in one" track/wheel setups.
I've been using various plastic circle templates, panzer putty to hold the wheel (in tire color) in place behind the template and blast it.
I don't see anyway to get that consistency

I was thinking maybe a heavy gray, neutral or black wash on the wheels then some spirits with a micro brush to clean up the centers a bit??
Thanks in advance guys for any ideas
