Anodized aluminum polishing
« on: December 11, 2016, 09:18:07 PM »
Is it possible to restore the luster to an aluminum trim piece that has once been re anodized clear as in bright and shiny  from original condition,  to bring back some of the "POP" that is achieved from a freshly anodized part without striping and re anodizing again. I'm not sure if buffing an anodized part will ruin it.

I have yet to see a process where a anodized part that has faded can be brought back like it looked  when fresh. Striping and re anodizing is the only solution I know of. Maybe someone else maybe knows different.

FYI to add to the equation is the fact that the aluminum exterior and interior anodized trim parts are for the most part not regular anodizing but a different process called brite dip anodizing . Regular anodizing on a aluminum trim piece looks dull compared to the same part that is brite dip anodizing.

It is my understanding that it is the anodize coating that turns cloudy over time from the UV and micro scratches.  The only way to restore luster is to strip and polish the aluminum base material.  You can re-anodize or leave bare knowing you will need to polish regularly. I chose to leave bare and apply a coat of wax.  I know it will require polishing, but not be susceptible to future fade and require the whole process over again.  It is also a lot more babied today that it was in the past.
