Anodized aluminum surfaces are sealed using a process in which one step involves bringing the anodized aluminum surface into contact for a relatively brief period of time at a relatively low temperature with a liquid sealing composition. The liquid sealing composition contains water, lithium cations, fluoride anions and at least one high capacity buffering agent such as boric acid.
