I'm getting ready to paint Italeri's LVT-4 and and can't find any references for the color of the bottom track rollers. The intructions suggest that they should be painted olive drab, but they are very unclear. I can't determine whether they are metal and should therefore be painted olive drab like the body; or if they are rubber and should be painted weathered black.

Also....are the tracks all metal? Or are they metal mounted on rubber?

Thanks for your help.
