The obvious idea is to put them on your laptop, but that can make reselling it difficult, and you lose those stickers if you sell it with them still attached.
So... I’ve managed to find some sticky-backed vinyl that looks almost exactly like the aluminium used on the MacBooks and MacBook Pro’s. I’ve stencilled and cut out a couple of lids and when applied you can barely tell they’re on there. They look awesome.
I’ve had them on nice hot laptops for a couple of months (with cool stickers applied on top) and they peel off fairly easily, but most importantly, leave zero residue.
I’m planning on figuring out if there’s a market for these ‘skins’ and going from there. I’ve take pictures along the way so I’ll put a blog together about it shortly, and gauge interest.
