Never powder coat over sealed anodised metal. It's like painting glass, just a case of when it flakes off not if.

Reference: "Why Anodised Aluminium should not be Powder coated!"

(Published by Dulux July 1994)

Anodising is a process in which the aluminium surface is "passivated": the chemistry is sealed and prohibited from bonding with any organic coating, including powder coat. As a result of a lack of bonding, differential expansion and contraction takes place between the anodising and powder coating, causing delamination. Anodising is not designed as a "coatable" surface, which explains the reasons why there have been dramatic failures.

Trials overseas have shown good results using unsealed anodising at 5 microns, although these methods still fail to be recognised by International Standards.  Whilst there have been local claims of success with anodising surfaces for powder coating, they are principally due to inadequate sealing of the anodising product to start with. Relying on such a process is extremely "risky" and in any case will certainly be inferior to chromate converted aluminium.
