PVD those fuckers.
Jokes aside, logos are etched, so acetone/paint stripper won't help.
I don't consider spraypaint a good idea, but if you do, why go through the trouble sanding them?
Edit: That being said, I'm curious how anodizing an already anodized/etched part might look like.
Thanks @mdcc_tester & @Jonny69 re the screw shrapnel lost in the DT
Another question that concerns me: how do i get the logos off of my Rotor3D30 cranks? Acetone wont help, so sand and respray it?
Any less annoying option?
