I have a new Dell Precision M6600. I want to personalise it. Being a graphic designer with a penchant for typography, I'd like to have text all over it (haven't yet decided exactly what). However, I'm not sure what the best type of paint will be for staying on, not getting too dirty, not rubbing off, not causing problems with the computer (though the fact I'm only planning to put it on the top of the case should help with that). Apparently the case is "Aluminum and magnesium alloy". Any suggestions? Spray paint might make my life easier, for making a stencil and getting the text on, but pot paint is viable too, as it's also stencilable, just slower and easier to mess up.
