get out of silent mode / reset car alarm?
why don't you just use drywall mud, or as some call it spackle, or joint compound? it's already mixed
I don't think it would be reflective. Metals are reflective because outer shell electrons dissociate from individual atoms and form a cloud. Electrons interact with photons, causing the reflection. As there are no electrons in neutronium, I suspect it would be dark.
