Yeah that was the first time I see such approach in production.

I also had to 3D print parts.. luckily those are for interal uses (drive rails), otherwise I would have loved if this paint thing was figured out as I could then spray paint the printed piece and color-match it with the rest of the computer case.
I have a Cambridge Soundworks 2.1 speaker set that have yellowed (or rather, oranged) badly on certain sides... maybe they're good for an experiment...

Regarding paint rubbing off, there are also protective coats to prevent that.. But I tried a black satin-finish primer+paint spray combo can, and it ended up quite solid. Just keep in mind:
- Don't spray in an open area where there is air movement. Dust particles will immediatelly stick and sink into the fresh paint.
- Don't focus the spray for too long. Otherwise you will get droplets that slide down and clump at the bottom edges.
- Don't listen to the drying time claimed on the can. Mine said 2 hours, but it took 2 days to become fully dry and non-sticky.
I've seen shops color-match paints for regular paints, not spray can paints. Is there a technique to apply those liquid paints evenly on complex objects?
