Skully, your thread title brought back a chuckle to me.

About 6 or 8 years ago, in the local newspaper, Panama City News-Herald classifieds, there was an ad that spent about 2 months off and on for somebody wanting to sell an “8 Man Hot Tub”. laugh

I bet any lookers saw the ring in that tub and walked away wondering if it was hard water that caused it or something else.
