How many square feet of coverage is expected with 1 gal? I have a scraped steel trailer bed with surface about 6 x 18 feet I want to coat, then paint.

I used 1/2 of the gallon on a 9x8 steel flatbed. 2 coats. Worked amazing. It converts whatever rust it touches to a back hard substance. If you have rust scale it soaks it up and turns hard.

What is the shelf life of this product once opened?

There is a product called "End All Rust that I purchased in 2003 and just used it again this year 2023. A little clabber at the bottom of the jug, but it did a great job! Still working after 20 years. I can't see why this FDC wouldn't last at least half of those years. Rust converter is rust converter.

Can I apply this to a wet surface?

It applies just fine on a wet surface, but you're diluting it. That said, as always, you would probably have better results on a prepped surface.

If used on frame does it have to be painted?

No it doesn't. When cured, it will leave a black polymer finish that's fully sealed & waterproof. If you decide to paint it afterwards, use a high quality oil based paint.
