Hi Jenny
Ya ! The fast stirring got me too.
About the Skimcoat plaster ,its just another name for plastering.
Several different types are used, veneer mostly for the so called Skimcoat which is just the last smooth finishing coat.
From what I found so far plaster of paris is a softer type and veneer is a lot harder more durable.
As far as whats best ??? Sounds like Jenny found a winner whatever it is.
