"Yes aluminium can be coated.
And it does add an extra layer of protection when outdoor.

Aluminium does not rust but it can oxidise over time"

"Can Aluminum Be Powder Coated?

Yes, aluminum can be powder coated. Some manufacturers warn that the powder coating process could harm the metal’s integrity, but this depends on the powder coating methods being used. When carried out correctly, powder coating will not harm aluminum, and the resultant finish will improve the part’s corrosion resistance, wear resistance, and aesthetic properties.

Why Powder Coat Aluminum?

Aluminum is a lightweight metal widely used in both aesthetic and functional applications. While aluminum is naturally corrosion-resistant, some applications call for additional corrosion protection, achieved through powder coating. This process could also improve the metal’s wear resistance, change the color and surface finish, and create a reflective surface."

"Yes aluminium can be powder coated
It will aid to its durability
But I do believe it needs to be etch primered prior to coating"
