Powder coating a steel tank

[SDAnderson]

So what do you suggest to stop steel corrosion where the paint has chipped off?

Sell them and invest in galvanized tanks. No, seriously.

There is a product that you can use that will provide a spray on cold gavanization. I have seen it, but can't remember where. I would suggest that you do a search on the web to find it and use that product to protect your tanks.
