The last 4 Macs I have owned all had what looked like pitting or corrosion on them top of the edge on the front edge of the wrist rest right where my hands touch. It is not bad, but certainly detracts from the looks and even the resale value since it is not flawless - like the rest of it is. Question is this - are there any wraps that would cover the palm/wrist rest, go down the front edge and then wrap to cover the bottom as well. It will have to be one piece so there are no gaps. If not, any suggestions for what I can make myself? I have used clear wrapping tape but it just looks terrible and obviously leaves residue.
