RE: bronzing in pt/pd

Chris, If you are having your students coat and print with brush strokes
that show it will be easier to see some on many prints. It is easily done
with the use of a brush; foam or bristle. You can feather the edges of the
overcoated area, that where the neg presumably won't be placed, to allow for
some very thin areas. If thin were the only the answer you could see it all
over the place where thin coated areas were present. It also has to do with
coating solution used. If you are only using PD it will appear more often,
but can happen with PT as well.

Thinner coatings are faster than thick ones but are also less able to hold
the exposure before bronzing/solarizing (old expression).
