Using Tamiya Epoxy Putty for 28mm Miniatures?

Hey everyone,

I'm trying to dive into miniature sculpting, but where I live, I can't get my hands on the usual favorites like Greenstuff or Apoxie Sculpt. I did find Fimo available, but it's only in the soft and kids versions—which I'm not sure will cut it.

I came across Tamiya epoxy putty at a pretty fair price here. Has anyone experimented with using it for 28mm miniatures? I'm curious if it holds up for detail work and overall durability.
