All,

Just to highlight that Corrosion Block did a great job penetrating the OLD and rusted fitting on the Pressure Relief valve (PRV) on my hot water heater.

Discovered a hot water leak last month and thanks to this "online searchable database", I was able to confirm it was the PRV. Ordered a new one and when I went to take off the old valve - no luck. Used 3 applications of a foam product and even a 12 inch wrench to get leverage....no luck.

One nights application of Corrosion Block did the trick. Was able to remove the old valve without any issues!

Corrosion Block also helped to resolve an issue my windlass when I first purchased the boat 7 years ago. The interior mechanism/gears/plates were corroded and locked in place. I could not drop the anchor or even disassemble the windless to clean and lubricate. After 2 applications, I was able to disassemble, clean and polish. The windlass has worked great ever since.
