Enamel is pretty hard. I'd guess harder than the plastic of a CD.
And yes, a Dremel might be pretty harsh. As a matter of fact, the heat generated by the polishing bonnet even WITHOUT any abrasive / rouge might MELT the plastic or soften and allow surfact imperfections to heal.
A Dremel MAY be best for a single scratch, not an entire disc.
I sort of wish I still had access to a good microscope so I could run some tests.
I worked for YEARS in a fab that made Quartz Crystal Oscillators. I used LOTS of abrasives and by the pound. The 'final polish' was done with Cerium Oxide, which if memory serves was 1/2 micron grit size. But it's been nearly 40 years, so don't hold me to THAT.
Too much is never enough
