I generally do not wait the recomended ten minutes. I wait just long
enough for the sensitizer to stop being shiny. I find if I do not wait
for this effect to take place I get crystallization in the places where
the sensitizer was still shiny wet. This seems particularly prominent in
the ammonium based systems:ware-pradip,zia,argryro, warecyano.
