    I just discovered a pit on my MBA. It wasn't there yesterday!

    I've only had the computer for about 6 months. I don't know why it started now, and not when I was sweating so much on it last summer. I haven't even been using it that much over the last couple of months. *sigh*

    I wish I had put protection on it, because I don't want to hurt the resale value. How was I to know that I had Alien sweat?

    Can anyone recommend some good protection? I gather from earlier threads that Marware ($25!?) and Moshi ($20!?) are the best products. Do you have any other recommendations?

    Sweat isn't going to eat through the metal. Upload a pic of the problem and we can think of better solutions.

    I used to think that too (actually, I am probably eating through the coating). I wouldn't believe it if I didn't have proof right in front of me. Attached is a picture. It is a little, perfectly round-shaped nick in the surface. It almost looks like a tiny bead of water from above, but when you touch it you can feel the indentation.

    I can assure you that nothing but my hands have touched the computer. I wouldn't call myself OCD, but I keep my computer extremely clean (never using solvents--just damp cloth and compressed air), and I never eat or drink near it. OK. Maybe a little OCD :)

    Here are some links to others who have had similar problems. The little pits on their devices look exactly what I am seeing. Obviously, mine is not much now, but over time, I imagine it will turn into something awful.

    Needless to say, I am sad that I appear to be one of the few (?) people with acidic sweat who don't get along well with Apple's powder coating / aluminum.

    Actually its a known problem and for some folks it is an issue that they're MBP's do pit due to sweating. Just google mbp pitting to see the number of hits

    Yep. That reasonably priced one only seems to be for the Air. I am loathe to spend 20 dollars or more on this :(

    I have the Moshi one, and it works great. If you're that concerned about the condition of your MBP and protecting its resale value, spending $20 to help protect it isn't really all that bad, is it?

    No. Not in the big scheme of things. I could forgive the hard case, because I really can't see it, and I think it actually looks good. But this? Now I've got to use my computer with a wrist condom on. The alternative, is more pitting, so I guess I have no choice. I'll probably end up with the Moshi...

    It gets better, I had a MBP with pitting, and they told me it's not a known issue, they've never seen it before, and since it was only on one side of the palmrest, it must be caused by my watch reacting with the aluminum.

    I happily pointed out that I wear my watch on the other wrist.

    Eventually they replaced it when I complained that the power button was sticking (which it was).

    Besides the pit, my computer looks brand new and runs wonderfully, so I doubt I will be getting a replacement for this little speck. That watch stuff is pure crap, but in my experience, a lot of the geniuses aren't so smart. It really varies a lot from store to store, country to country.

    I got out my magnifying glass and I think I have found some potential future pits. I guess it is time to spend more money. I'll probably go for the moshi then.

    EDIT: Thanks for the help everyone. I purchase the moshi PalmGuard for Macbook 13" Unibody - Silver for $17.50. I wish I would have gotten this before the pitting!

    Not sure if situation would be covered but isn't it still under warranty? Might be worth a shot.

    thanks. my computer is under warranty. but, with such a small pit, i doubt they would cover it for me. even if they did, to be honest, it isn't worth going there to muck about with it. the computer is great otherwise, and this won't affect resale any more than the gas it would cost to drive out to the store.

    i got the moshi palmguard. i am seriously disappointed in everyone on this forum for not making it clearer to me long ago about how great a product this is. i should have gotten it my first day.

    Metals don't pit due to sweat, they pit due to the chemistry of the oils on one's skin. It's commonly seen on inexpensive jewelry and eyeglass frames. The only metal that will absolutely not react with these oils is titanium.

    It is however still quite rare to see that reaction with aluminum.

    Having spent several years of my life as an optician, I've seen some nasty reactions. Only once or twice with aluminum.

    While aluminum is very unlikely to pit in reaction to one's skin, it is a very soft metal. It will scratch and dent quite easily. It's structural integrity is great, but it does scratch easily.

    If your skin were reacting to the metal, there would be more than one pit. Plus, if you're cleaning it regularly, the oils are being removed. I wouldn't worry too much about it being an issue with your skin, it's far more likely that something came in contact with the surface and left a mark.
