Deoxidising after Anodising and prior to Colouring
I am having some difficulty colouring Anodised Aluminium and suspect I should be using a Deoxidant immediately prior to Colouring. Any suggestions for a suitable Deoxidant.

I've never heard of that, David. Rather: pretreatment, anodize, dye, seal (with rinsing in between each step).

The nitric in the deox will 'open up' the pores and allow better dye absorption in some cases, usually castings.

Thanks, Bill. I know of dilute nitric acid being used as a rinse aid after anodizing, supposedly displacing trapped sulfuric acid. Is this "deox" solution stronger, or is it also very dilute? Thanks.
