yes, the steel parts (barrel, cylinder and the housing if it is steel and was not changed to a later aluminum one) can be touched up with some good cold blue, we like 44/40 from Gun Parts, New York, works MOST of the time quite well on Rugers...as noted above the main frame (black/blue) and the trigger guard (gold/brass) are anodized and do NOT polish them out, underneath is silver( white) aluminum and when polished out on a Bearcat looks like CRAP.........many hammers are partially blued,top, front and back, the sides polished.........wide spur on your gun prooves it is the "safety update" conversion,it is a nice touch......still looks like a very nice gun overall..... :wink:
