Apple :: Palmrest Paint And Temp

I swung by the apple store recently, and checked out their 15" mbp (since the 17" wasn't/isn't in store yet). I put my hand over the palmrest to check out the keyboard layout and that particular laptop's left side palm rest area was pretty darn hot!

This brought up 2 concerns:
1) With the heat and the skin/oil contact with the aluminum surface, will that ruin the paintjob faster? is there even a paintjob or is the silver color the aluminum's natural and only color?

2) Regardless if the paint comes off or not, is there a way to make it cooler and more comfortable to type/game on? For those that play fps games or WoW, we all know our left hand is pretty much in the same spot, and if our wrists are constantly getting a spa treatment, it's not going to be very comfy. I know there was that ilap whatever thing you place under the laptop to diffuse the heat from concentrating on your laps, so I wonder if there's something like that for the hands.
