Regarding Bill Plunk's "Replicating Red 421" in the July issue.

Bill is correct. Outer surfaces were painted the base coat while the inner surface was just left in the red oxide primer. This was done on all panzers.

There is nothing stopping you painting the inner surfaces of your roadwheels the base coat colour at all. 

Thanks for the info snap.  Just for something diffrent, next panzer gets the inner surface primer treatment.  

They’re gonna get covered in dust, mud, and muck pretty quickly in use anyways. Not to mention that those substances along with any track guide teeth will start wearing away any paint or primer on the inner faces of the road wheels.

Thanks Stik.
