Alright,

I'm running about 12% sulfuric acid. My part is 82.6 sq. in. Running about 2 amps @12 volts. My calculations have me at 216 minutes. So I am thinking I should up the acid concentration which would increase the current draw and decrease my time.

But I am thinking that I may not be getting the dye sealed fast enough. I am dying in a cold bath about 80 F up to 30 minutes. And then sealing for about 25 minutes at 190 F. Sealant turns pretty dark so I am losing a lot of dye.

What do ya' think, should I heat up my dye bath?
