Caswell Inc. - LCD Aluminum Anodizing Kit I bought the standard caswell anodizing kit over a year ago with the idea to anodize a colored lower. Never got around to it and it's taking up space. Does not have the electronic power supply - I was going to use a battery charger. I do have a gallon of battery acid to go with it. Check the website for details. I bought for $399+ Make me an offer / trade.
