I'm a new member, too, and I'm having a problem with my polycoat finish top. when I first got my gun, about 3 months ago, the finish was very smooth and a little bit shiny. After cleaning it and putting it away, the finish has become very dull. It looks almost like anodized aluminum. To clean it, I used wd-40 to flush out the inside, Hoppes #9 in the bore, and then oiled it. What could cause this change in the finish? I'm bummed. It looks like a Sig Sauer now.
