whats a GBP? do you mean MBP (MacBook Pro)?
my Core Duo MBP has suffered from corrosion (black dots) from sweat on the trackpad where my palm rests for trackpad use and on the left side. it happened ages ago and has not enlarged. probably because i keep my hands clean now.
GBP = Glassbook Pro![]()
I use clear packing tape
Wouldn't that leave a nasty + sticky residue when you remove it (or when it becomes worn by itself)?
