As a tank inspector let me add a bit on this subject. Powder coatings can be applied in a couple ways and there are a couple ways in which the metal is prepared as well; one method requiring a chemical etching and the other using sand or glass bead blasting. These are used to prep the surface to hold the new coating. With scuba tanks it has always been advised that you not alter the metal in any way including sanding. After the cleaning and applying the power coating the process requires powders to cure at about 400°F. Again something that is not advisable for scuba tanks. Lets say you do get this done there is yet another issue. When a tank is inspected if something is felt under the paint, yep that salt water will find its way in then it will have to be stripped to inspect. Tank makers go to great extremes to ensure that their products will last you for decades with proper care. It is my opinion that if this is done you put yourself and others at risk. I for one would not fill it knowing what was done. My .02cf worth
