Difference in "colour" of anodized parts
We tried to anodize 4 parts(2 were 1 size & 2 were another) in the standard 5 gallon pail all at once. There was a total of .65 sq. ft. and we tried anodizing at 12 amps/sq.ft. The rectifier zeroed out after 32 minutes. When we took the parts out, the 2 outside parts were noticebly lighter than the 2 inside parts. Should we buy more lead to cover the entire circumference inside the tank? Do parts need to be identical in size if trying to anodize more than one part?
