Ah, cool. Any idea what sort of paint he uses?
IIRC the main advantages to the vinyl dye is that you can use it on things like keyboards/mice/buttons/&c. that see a lot of handling and it won’t wear off like normal paint will, and also it’s less likely to obscure fine texturing, but the downside is that it usually doesn’t come in quite as many colors as other paints do.
I’ve also heard mixed reviews on things like Krylon Fusion which supposedly “bonds” better with plastics than normal paints, although still not as well as vinyl dye. (I think it has extra kinds of solvents added to it compared to most paints to accomplish that?)
Or maybe he has some other sort of more specialised paint that I don’t know about.
(On a side note, another fun option might be a run of transparent shells. Kind of like those transparent phones that you used to see now and then, where you could see all the insides. Whatever happened to those things, anyways? Or the inside could be painted for an effect similar to the older iMac/iBook-style devices perhaps. I’m sure people would come up with all sorts of ideas for such a thing.)
