Hey guys
I'm in mainland China, Foshan, may provide some advice and assistance to you, but to my understanding the surface to be machined to a perfect treatment, at least 6063 aluminum to the surface oxidation process no produced obvious flaws.
Of course, if you do paint the surface, then the problem is no need to worry about.
