Switching laptop bodies?

I have a Toshiba laptop, and the top of the body where my palms rest are very smooth and so are all the keys on the keyboard. I dont have any other problems anywhere else except for those 2 spots, I hate how it picks up the oils on my hands, and just looks like **** and I kind of dont like how it feels. If I could I would love to have a roughed up kind of feel in those two spots, that way my prints wouldnt be every where. Is there anything I can do about it? Like maybe scuff it up with sandpaper or something to take that sheen off, or is there a way to just flat out switch the body and keyboard? Id rather not switch bodies if thats even possible, but what else can I do?
