I have been in the Anodizing industry here in Australia for over 12 years now, and what you say there will pretty much work fine... as to the quality of the product that will produce, its pretty hit and miss, Probably with the sealing process with the boiling water will be the downfall as just boiling water will not fill the pours that the anodizing creates that is why most Anodizers will use a solution that contains nickle. But give it a go people if you have the time and patience for it, i have my own little Anodizing plant in the shed and it works great, Nothing compared to the 17v 5000amp i use at work but it does work
