I use a mix of about 70/30 by volume, spackle to Durham's.

It's a great mix for the white foams. I use that material as well.
However, the florists green foam as a plug can handle bondo. The cure time is minutes. The sanding is easy. If you can handle the smell. Be outdoors when using it.
Don't get me wrong, I hate bondo, but it makes short work of a plug of green florist foam.
