Hello, I'm planning on getting the carbon fiber (black) icarbons stickers for my rMBP 15". I had a few questions for all users that have experience with icarbons. 1. Does the adhesive leave any residue behind on the MBP's aluminium finish when taking it off? 2. How likely is this skin to cause pitting on the MBP, I know peoples sweat sometimes cause them. But have you guys had any issues with your MBP's eroding or pitting caused by the adhesive? 3. How easy is it to actually install? 4. Any heating issues caused by having this on? Thanks!
