platinum chemistry

I was reading in one of the online FAQ's that after mixing the platinum
with the Ferric oxalate, you should let it sit for an hour before
coating. I'm currently working with Ziatypes.. is this necessary for
this process as well? Since I haven't been doing this, what gains should
I see?

     Thanks
