Thanks Benchmark!
Bookmarked to try on some old rockhounding tools and a cast Dutch Oven that got on upper shelves somehow and forgotten. 3.5 miles from Atlantic here, and sea breeze reaches me sometimes.
Usually keep ahead of rust, but you forget a tool in garage for a few years..and you have some time consuming work ahead of you.
Dad lived right next to 105 mile long lake, and 8 foot wall on 3 sides had earth banked up and poor drainage.

G. sounds much safer...I just thought I had to mention.
Thanks again!
