I have never used vinal dye so i am very very curious how your 360 turned out... and strange enough i have been thinking of doing my wii and horizontal stand black also XD
So if the dye really does work out well that will be the likely choice for the wii+horizontal stand
its great, it does not run. it absorbs right into the plastic so it is less prone to scratching, leaves no streaks. and retains the texture of the plastic.
unlike spray paint. you can find it pools in labels for example the top of the console says XboX 360 etched into the plastic. with paint that could harden and cause a mess. with the dye. it just soaks in and everything looks factory.
