Since It's near impossible to find the eccomposites type fillet wax locally I'm going to try dental utility wax. It is soft and easily molded and pressed and will be easy to fillet into edges that need sealing. The melting temp is in the area of 70C. I'm assuming that it will release from resins easily as well. Even it if doesn't it will be easy to scrape off. I will have to see if the stuff will be dissolved by the surfacing epoxies but it shouldn't since epoxies don't really have any solvents properties.... 

Also, with the quick pass of a butane torch the surface will liquify ever so slightly allowing to essentially re harden in a polished-like state.

Nah it's not. Beeswax is harder, I've got a pot of it here for woodworking. It may have Beeswax in it but it's not pure... 

just use modeling clay

I'd say both of those will be much harder than the EC filleting wax. There's no way you could sculpt or carve the EC stuff, it's extremely soft. 

So I haven't been able to nail down a source in Canada/US for the Easycomposites yellow fillet wax.

This looks very similar.
i have filleting wax form EC, but from structure and smell defenetely looks beeswax.

so maybe anyone with no access to buy, could try this recipe.
