How does one prepare and apply this product? Is the water/product mixture paste-like or watery?

Dissolve it in hot water. Will be watery. Scrub hot solution in with a brush. Then make sure you clean it up with water after don’t leave any residue.

Can you use this on a metal rusted roof?

I have used it on metal corrosion on our fleet of sailboats for years and have been very pleased with the results. I have tried other products and found that almost nothing else works. If you plan to repaint after removing the rust/corrosion you will need to make sure your wash the surface several times with fresh water. For stubborn areas, you may need to do a little wet sanding with very fine sandpaper (300 GRIT or higher). If you have any wood in the area that you don't want bleached (e.g. a wood deck or stairs) you should cover it and then hose it down as soon as possible if any of the oxalic drips on it.

Is this a good product to use for removing rust stains on pavers and travertine? What is the mix ratio?

I have successfully used about a tablespoon per quart of water for removing paver/concrete rust stains.

Can a mix be used to remove rust from inside a fuel tank? I would think it would be more gentle and less likely to produce pin holes .

Yes. It works well. I have used it in a Ural gas tank, which was stored for 13 long years with bad gas. This stuff in hot water removes all rust pitting from inside the tank. I had to use baking soda mixture to neutralize the process. I then used a pint can of the Red Kote to line the tank. Great results.

一般人が購入できるものですので割高です。

本商品は法律上劇物指定を受けているので一般の人は購入できません。これは届け出なしで購入できるのでまぁそれを踏まえると仕方ないと思えるかもしれません。
