Shortage of hot dipped galvanized tanks in the US?

After a while, even the hot-dipped cylinders need some touch-up - the hydro stamps can flake some zinc and develop a little corrosion. I used the spray cold-galvanizing on mine...
Perhaps, but not on mine. HDG is essentially "self-healing" I've been told, but I'm not a chemist nor chemical engineer so I have no clue if that is actually true. But I do have 6 HDG in total, 4 with original born-on dates of 2007, 2008, 2008, and 2011. A lot of hydros on these 4 tanks. Not a speck of corrosion on any of them.

Exactly. I paid a bit more than that for 2 new Faber HDG HP120s (~$700 total) a few years back. And last year I paid a lot less ($400 total) for 4 PST HDG HP100s.
$600 for one is nuts. The Rustoleum solution sounds a lot nicer for just a cosmetic upgrade.
This is what some of mine did. I took a wire brush to them to remove the suraface oxidation, then hit the area with the cold galvanizing spray. My cylinders spend most of their time in fresh water too... Rest of the surface looked good - the only issues were where the stamping had resulting in some flaking off of the coating.

Should have used a bronze or copper brush. The corrosion in your picture may be more caused by iron bits from the brush itself.
Same corrosion issues happen to stainless steel tools if they are ever used on iron fasteners. The microscopic bits of iron transferred to the tool will corrode and stain the stainless steel.
At this point I don't recall which brush I used - it's likely I used the "brass" brush from the little set of 3 that I have, but it's been a while. The rust happened before any brushing occurred, and I don't think it's come back since. The chipped/missing coating in the above pic is the factory stuff.
This is the cold-galvanizing that I used:
