Default Re: fingerprinting issues on anodized alum.

What alloy, CD, tank temp, and sealing process are you currently using?
It could be desolution... is the surface chalky?
It could be lack of thorough sealing... are you steam sealing, or using the nickel acetate high temp sealer?
I use the nickel sealer at near boiling temp for 20min for .75mil, and 30min for 1mil ano thickness.
