Are you sure that's a V3? I have had a V3 for two months and the finish is like new, even though I drop it into a 7/8" drilled hole in my mod stand, knock it around on the desk or counter, etc. It has minor nicks and a tiny scratch here and there, but the finish is holding up well.
Also, underneath my gunmetal black chrome plating is the brass the thing is made of. I only know this because I used an awl to "mod" the mod by removing the plating on the little round inset thingamajigs on the top cap.
