Removing anodized coating

Aluminum is anodized to prevent the aluminum from corroding. The process converts the surface layer of aluminum into an inert aluminum oxide. It is best to leave the anodized surface in place and to use an aircraft aluminum polish to brighten it up.

If you remove the anodized layer then you must treat the surface with something to prevent corrosion such as a chromium containing primer (aircraft). If you are going to get some items re-chromed, then ask the platers if they do aluminum andodization.

I have worked in the aircraft business (Douglas Aircraft/Boeing) as a materials and process engineer for the last 25 years.
