Nick, great idea. Do you do anything special to prevent the napkin from moving/falling?
I'm not impressed with the impact of almost two years on the hardstand in Scotland. I have a bunch of "stuck" systems around the boat needing stripped down or replaced, and it's proving difficult to buy Corrosion-X locally. On the bright side, the weather is fab here right now and my new hybrid lithium/lead power system is working superbly.
