To me it's the exact opposite of finding the rifle with original grease, crud buildup, and surface rust. It's a positive previously owned by a collector sign. It doesn't necessarily mean anything bad, but it does make me look for fakery alot harder.Arch - I agree with your comments about scratching and it being used by some to hide problems. My inclination when I run into such white markings at a show is to recoil a bit and become more suspicious. By no means a kiss of death but anything that initially makes me recoil and become more suspicious generally results in a lower offer unless I can get it removed then and there.
