Hi Andrew. I dont know if it works. I have it bookmarked because I have been collecting (real) tin cans for the past six months to make tin tiles for a roof- probably of an outbuilding. This tin is coated, but it will eventually lose that coating, I am sure, so I had thought of using this product when it becomes necessary. The added benefit is that I could use the roof for rainwater catchment. So, if you try it, you can let us all know if it works! Haha.

That may work for aquaponics setups, too. but it is pricey stuff.

Yes, and further to both comments, that I am saving tin cans for a roof is absolutely evidence for how affordable that rubber is to me presently...

Bitumen is another name for asphalt. Not sure that's what you want for water catchment, but that's your call.

Everbuild EVB90101 Black Bitumen Paint is a solvent based, full bodied black bitumen paint. When dry, the product forms an odourless and taint free bitumen film suitable for the protection of metals, concrete roofing, felt, fibre, cement, corrugated iron, asphalt and wood against water attack. This product has a fast drying time and is suitable for use with portable drinking water tanks.
most builders yards have similar products extremely good if you re-coat every 3-5 years i have seen 30 year old tanks rust free only problem nowadays is painting in confined spaces

cut any structurally unsound parts of the rusty roof...replace with your tin can collection. if you can sandblast the rest, that would be best.
now you have a substrate for ferrocement.
get nylon fibers to mix into the cement. that allows you to use a thin lightweight layer without cracking.
the only drawback is that it is then an alkaline surface; but if you can live with that while you save money for a favorable sealer. we have acid rain living here by an active volcano so it can balance...I don't know what would be a good sealer...some claim safe for catchment...but they are selling it.
