Reminds me of a story. It was 1967 and I was in USMC bootcamp and every Sunday there were a few hours of time for yourself. You needed it to polish boots, shoes, brass or write a letter. Anyway one of the recruits, who wasn't the sharpest tack in the box, is busy using steel wool to remove every bit of blue from his M-14. By the time I noticed it he was maybe 90% done and a fine job it was. Maybe 15 minutes later a drill instructor walks through the area and takes our bright young fellow down to the drill instructors hut. This was a place you definitely did not want to go because you rarely saw a fellow return from their hut. They just disappeared.
