I've read a lot of UK articles about making scenery and they often describe techniques using Polyfilla but I live in the US and there is nothing called Polyfilla. Anyone know what Polyfilla actually is or what the Home Depot equivalent is?

So let me see if I've got this right

The stuff at Home Depot called "Spackle" is like Polyfilla (i.e. plaster with plastisizer)
Hydrocal (can you get it at HD?) is just plaster.

So then what is "Lightweight Spackle", it seems nothing like plaster although it does seem similar to Woodland Scenics Foam Putty?

And then what is Woodland Scenics Lightweight Hydrocal? How can you make plaster lighter without making it out of something else?
