Yeah, unfortunately HT is going to dumb-down their paint with a lot of weathering.
"dumb-down"?.. you mean make it more accurate? at no point in the movie was the armor this pristine. don't get me wrong, it looks very cool. but even when iron man first puts it on, it's not this clean.. and it only gets more scuffed from that point on. so, while you may think it's dumbed down, i think the hot toys version looks more realistic, and weathered paint job just looks higher in quality (to me of course).
