.... So for tires/wheels you use Anthrazite. Exactly what is it, and can you post a link to the paint/color for me?
The paint I use comes from Revell Germany and is called No. 36109 Anthrazite, though I'm not sure, if you can get Revell paints in the US. Sure not at the moment ....
It's also known as RAL 7021 Schwarzgrau (Blackgrey), a german standard, but widely used. You might look for this on other paint brands.
As I said, I use this colour on all tyres of my builds, aircraft and AFV. Here are the tyres painted on my MAN 5 to truck I've built during last years Logistic Campaign on Armorama, so you get an idea how it looks like ....
Of course, it didn't stay that way after some weathering ....
