Ok im using a LCD setup with a CC power supply. I want to go by the 720 Rule. Im looking for a .5 thickness so I think that means I need to run it for 80 min. But I am confused on the furmula to figure out surface area and how many amps to set it at.

Im anodizing a paintball barrel that is 12in long. I wrapped a piece of tape around it and figured its about 3.5in around. Thats as far as I got. How do I figure out how many amps to use. And I know I have to calculate the inside as well. Any help would be great.

I tried using 2.5 amps and the volts starting climing. And after about 5min it was at my PS limit (13volts.). So Aparently I dont know how to calculate very well.
