Can the aluminium used in Apple products have impurities which can cause small black dots in it?
The small black dots some users notice on their macbook pros is due to their skin's oils or their sweat corroding the material. They usually appear on the palm rests of the computer after a few months to a few years of use.
But I've heard of people seeing it there the day they got it, even if its almost unnoticable. I've also heard of very small dark patches being on the material. So I would have thought these are either impurities or small manufacturing defects.
Its often called pitting.
mine happened after I dropped some USB cables that made tiny chips in the coating... The sweat got in and ruined the laptop.
Just like car's finishes, if you don't take care of the nicks, the "cancer" will grow over time.
So, do they bother you enough to warrant a partial refurb, clean and clear-coat each nick but may leave un-even blotches, or a full refurb, disassemble everything, sand and re-clearCoat (very time consuming).
The **** are you talking about? There's no clear coat on Macs
Yeah what are you talking about?
I will stop responding now due to foul language.
The finish you see on the Macbook line isn't the actual aluminum metal. They've been coated (anodized) to give them the silver textured finish, so that's actually what you see.
I guess it's possible that there could be specks or flaws in that anodized coating, but I don't think that's from 'impurities' in the aluminum.
What about dirt or dust of some sort from the factory? Could these cause dark patches in the aluminium? What do scratches on these products actually look like ?
Can someone post pictures of what this looks like on a MacBook?
