I've been mixing 2 scoops of mason's Lime into my batch mixture
this is at a point well before your finish coat situation.
Troweling it smooth seems to work well and after a bit of a rainy few weeks, the mixture seems to hold up to being almost completely exposed.
so far
If the plaster is on the outside, then I don't feel like the heat will have any effect.
what little water you get onto the outer surface shouldn't touch it either.
Granted, I haven't done a thin lime layer over clay, but there seems to be no significant shrinkage differences with what I have done
mixing lime into cob will make it a little bit caustic on bare hands and eyes
so be warned
just don't mix up the pure lime with your bare hands or anything and you'll be fine
