My first thought was, "I doubt it. Who wants to spend ages scanning cards with teeny-weeny dot codes (that frequently refuse to read because the sensor got blocked with dust) just to get their car's paint customized the way they want it?"
Of course, Nintendo's e-Reader peripheral for the Game Boy Advance hasn't been relevant for a good eighteen-ish years now... :/ (Unlike in Japan, the e-Reader wasn't very popular overseas.)
Still, e-ink paint is pretty cool. Might kinda suck for anyone whose car gets badly scratched/dented and the place they go to tries to match the paint color without realizing it's special paint -- 'cause if you change your car's color, then you're stuck with spots of the wrong color --, but as long as they're not changing their car's color very frequently, they probably won't even notice. :)
