Hi Witho:
I have never try it. According to Carl and also is written in his book in
collaboration with Sullivan, they mention that this is not possible.
What are you doing that it is different?
Regards,
Alejandro

Alejandro,
To make a pure platinum print there is no need for brush development. Just
use ammonium ferric oxalate and process as a POP print (Zia). If you don't
dry the paper completely after coating then there is no need for
development.
