How exactly do I go about shipping a pistol off for work/refinishing? The recipient is an FFL. Do I just box it up, bring it to the nearest UPS hub, have them slap a "Adult Signature Required" label on it and ship it out Next Day Air? I know not to put anything on the outside of the box indicating that it's a firearm, but am I supposed to tell the UPS folks that it's a firearm?
Input from those who have done this before would be greatly appreciated.
