You do clean it first before you fire it, and not vise versa, as the way I read your post, right?
Can't speak for the cosmetics, but I'd inspect it, and clean it very well, and make sure the latch area and chamber are clean from oil or grease, but especially make sure to run a few cleaning patches down the tube before you fire it.
It's just a good practice to get into!
Good luck, and let us know how it did at the range!
