1) Black 3.0 2) Musou Black 3) Singularity Black

Found a reddit post of someone saying they painted their laptop with black 3.0 but the paint rubs off and its not something they'd want to handle on a daily basis.

Best I could find is a video of someone painting a laptop case with musou black https://www.youtube.com/watch?v=mwvSX12MITk which while looks awesome it also looks like it would rub off on everything you own so probably not realistic either.

Did more research and found this reddit post of someone who anodized their macs: https://www.reddit.com/r/mac/comments/wswe1r/my_anodized_mac...

Now I'm wondering how dark a matte look you can get using a similar approach.
