Joe I also use 2 full strenght coatings for the final print, but my drop count is lower than Clay's, I use 1.2 ml total. 8 drops FO, 6 drops PD and 2 drops PT. I second Clay's advice to get the Richeson brush, you will see a great difference from the rod.
Drying the second coat with a hair dryer like Michael said is a good idea, when I let the second coat air dry I found it was very hard to clear the print, sometimes it did not clear completely, ruinning the print.
Lallan, sodium platinate is the restraining agent itself, as opposed to sodium platinite which is the image forming metal. B&S has a good article on this if you want more information.
