T26E4 "Super Pershing" vs Panzer IV/70 (A)

Hi MM: I know that AI is open to suggestions. It appears that on the Pershing, there is extensive decal silvering.   Also on the JdPz IV, his worn paint patterns strike me as unrealistic.  For instance, look at the worn pattern on the saukopfblende armored mantlet.  What would scrape paint off of that front edge?  Just because it's an edge doesn't mean it should be shown with worn paint.  Many instances of chipping and wear do not correlate with areas that would be in contact with crews' shoes/hands or scraping by branches or thrown rocks.  Hope that makes sense.
