Hey what's up and what is your mystery substance would love to find out what it is and how to make it thanks

But then it wouldn't be a mystery anymore.

Didn't one of the gunge stores do limited runs of metallic-effect gunge? If they did a pink one at some point, it's probably that.

First rule of the mystery substance, don't talk about the mystery substance.

Whatever happened to a bit of mystique?

If I can't tell what something is I'm impressed.
