Well, I was doing some photography for my first book and had to substitute a similar but incorrect cleaning rod for the picture. To make matters worse, the rod was an inch too long, so it couldn't actually be in the groove. I taped it (out of camera view, and thoroughly) so it wouldn't move, and lined up the shot, very carefully. All went well - you cannot tell the rod is not in place - until I went to remove the tape.
Oops!!  I've smeared all manner of "stuff" on the raw "bands" and while the color is almost right, the gloss level isn't, yet. I'm still working on it.
