That looks great but I don't think it'll work on painted matte plastic. If it did, man that'll save me hundreds of bucks.

Maybe if you could treat it somehow it would stick. How does nintendo do it?

That's a good question. I'd imagine the cases themselves are laser printed. I'll have to find out. Because again, this method is so much more cost effective. Printing the image is nothing, and I'd just need sandpaper, the acetone/xytol, and a resin or sealant of sorts to make it permanent. That shouldn't cost me more than US$50.

Also, that guide said Xytol, but a lot of them use a blender marker, which is like $2 at a craft store. If you get the marker though, check the ingredients in it. A lot of them are water based rather than whatever chemical it needs to have.

Marker looks nice too. So I'll look more to see how to do the Swirl with this method. But that still leaves the buttons themselves, which will need to be dyed. I don't want them to look too opaque though, as they have to be soft and bright colors. So I'm wondering if that means I'll still need the airbrush.
