Clear Coating Raw Aluminum

I have always been old that Aluminum is an "active metal" and that you cannot just spray any old lacquer or polyurethane on untreated aluminum. And, the treatments required cause a yellow/green color. Is this true? What can I use on Brushed aluminum to keep the black oxides from getting on everything that touches it?
