Hi Guys, I would like to know and I am worried, is it possible that with continuous usage and resting my palm on the palm rest area on the 15" Touch Bar rMBP it might wear off some colour because of continuously keeping, resting my hands on the Palm Rest area ? can the aluminium coating come off with usage ? it has happened in the past and that is why companies like Moshi would sell it in the past for the earlier models of the 15" rMBP. So do you guys think I should put a palm guard there ? is it needed ? I am also just curious to know if any of you guys use a Palmguard and a Trackpad protector from any of the 3M stickers ebayers in China and Hongkong ? how are they in quality ? Do they leave any residue after removing ?
