I'm assuming when you say without that you're suggesting that the  
chlorate be added to the ferric solution just before printing?  Or...  
what method are you using?

Not sure how to mix coating solution #2 without Chlorate since it is  
the only difference from sol. #1?

How does one do this?

This is why I made the post, to find out what others have used and if  
and when adding the gold is there any benefit to adjusting the  
Chlorate in sol. #2?

I have only ordered PD and PT in solution so far but I'm looking into  
the powders.

I'm fairly happy with my prints but am always looking for ways to  
improve them.  Still photographing with film but printing with digital  
negs.  Most of my prints are made with 1:1 solution #1 and #2 and if  
not just a slight drop change.
