One of palm rests of my 2 year old MBP is highly eroded (7cm damaged edge, sometimes up to 1.5mm width new surface revealed, some .5mm deep erosion) due to sweat (?). The same surface appears to be more exposed by an offset top lid (lid is offset by up to 1 mm or so). My MBP is still covered by Apple Care. Do you think it's feasible to get a case repair / replacement? Had I known this potential risk, I would have bought a protective case and avoided the problem.
