What sort of coverage can I expect in SQ feet?

I never thought of Rust Free in terms of sq footage as I only use it for the odd job. If you're thinking of using it for a significant "project" with lots of square footage, I would think there's probably easier, and cheaper ways that bottle after bottle of RF.

Where can i purchase more rust free it says its unavailable now ?

Naval Jelly is phosphoric acid as some comments reported the same for RustFree. Best Price in the Midwest state area is green box store. They sell 8 ounces of brand name "Rust Dissolver" aka "Naval Jelly" at $3.98, after 11% rebate it is $3.54. The Navy has lots of rust to remove on destroyers . air craft carriers etc. Hence the name. Works WELL.

Does it work on lamp posts?

Not sure about lamp posts. I use it on my wood working tools. Planer, table saw band saw. All of which have a heavy cast iron top. Works great

Will this work to remove light rust on a stainless steel table?

I use this product (which is an acid) with a Scotchbrite pad for removing rust from my cast iron table saw top. It should remove light rust from stainless steel, but I would not use Scotchbrite pad due to surface scratching. (Maybe use a rough terry cloth towel). The acid may discolor the surface.
