I used ethyl acetate
to remove the stamp. But wait! I can still see the stamp!
The disc is a Star Valk.
I used the nail polish remover to get rid of the stamp, and it looked like
the stamp was completely gone. When I got a closer look, the stamp was still on the disc clear and untouched in this new condition. Is the stamp engraved onto the disc? Is there any way to get this off?
It looks kind of white in some places of the stamp (like I didn't do a good job) but most of the stamp appears scratched in, perfectly but without color and the second layer of silver.
