Resins+EVA Foam (Australia based)-Can't get typical stuff, looking for sustitutes

Hey so I've been researching a lot on the sorts of resins one would use on EVA foam to seal/harden/prime a build. Normally I'd straight away get the Epsilon or Smooth On 65D as recommended by Punished Props but they aren't really sold here in Australia and they are expensive to order online. I don't suppose anyone from Australia(or just anyone super-knowledgeable on this stuff) who uses these forums could recommend me some substitutes?

It's really overwhelming.
