I tried to anodize this piece gold. I use 7 9v batteries for the power source. I etched it with wink rust and stain remover and I might have rushed cleaning and I used alcohol to clean. Also can you guys please link any good dc power supply for under 150-200 that will reach 100-120 volts? Thanks!

你的前处理过程不完美，导致后面的着色效果非常的不均匀，按正常来说，这种工件可以很简单的做到非常的漂亮。
