You've got knowledge that I don't.. I don't know what the polish does.
But I do know that a lot of people change a recipe they've never tried,
and then complain that it isn't very good. The least I could do (without
really understanding how or why something works) is to follow the posted
process first.. after that, I can experiment.

ok, now I'm ready to experiment.
So we're saying that plain old plaster of paris works as a marking agent?
yes. the p.o.p does the trick.
