I've been mildly addicted to Threes for nearly 13 years now. It's my go-to when having to wait for anything, which is especially handy when you're as impatient as I am (getting old). Also keeps me from doom scrolling. Just best score chasing, run based, number matching goodness.
Could plasti-dip the case also. But like you suggested, a can of Rustoleum and be done with it. Or just have the kids sticker bomb it.
