Recently i laid my MBP such that it's alu bottom lies on the surface of iLap, i thought by doing this it will allow my MBP to cool off faster. No doubt, it does cools my mbp faster coz heat is transferred to ilap and the bottom of ilap is exposed to open air. But just a few days back when i lift my MBP, i saw iLap's top was somehow stained with some black marks, i suspect that due to my MBP rubbing it accidentally when i try to open the lid, plug something in to the USB ..etc. I bought some fine sand paper, trying to sand it off, and sad to say, the stain does went off but that particular area which i sanded is gone. It being scratched quite badly, i tried to use Autosol to polish it, doesnt help much, anyone know what should i do to make that part like a sand-blasted Alu surface again??? Anyone..
