Has anyone tried putting on one of those skins like the invisible shield on the Macbook Pro and then putting on a hard case like the Speck SeeThru Case? I was wondering if the Speck case would fit on the rMBP once the skin is on. I have a Incase case on my 13 inch and it makes these tiny craters in the metal that I cannot get out, I don't want the same thing to happen to my $4k MacBook Pro when I get it, so I was wondering if I could put the Invisible Shield on first and then put a case over it. Anyone ever try this?
