Actually My XD has a little rust on the slide. Gun oil and a piece of cloth gets most of it off, you can use a nylon brush and get the rest off usually. Doesn't do any "damage" that I know of, but it's cosmetically annoying. +1 to what others said, little extra oil. @1000, what year was your XD made? I actually called SA about mine and the told me they switched some finishing one year and I got screwed, but since it was over 5 years old they couldn't do the repair under warranty
