I have a question regarding the silver glaze coating on the body of MacBook Pro. Does constantly keeping your hand at the palm rest area on the MacBook while typing on the keyboard, can it lighten the silver glaze coating or leave stains because of sweating and thereby peel off or wear off the silver glaze coating on the palm rest area?? This happened with my Sony vaio constantly keeping my hand on the palm rest area (like for e.g for typing on the keyboard) on vaio has left some stain because of the sweat of my hands on the palm rest area.
