:Do I (black) patina first then rub in putty?
I never use patinas on came. If I want the came darker I use a black cement, then in the brushing phase it gives the came a gorgeous black luster. Even without a black patina, a proper brusing will darken lead substantially.
I don't recommend putty though. Use a cement specifically designed for stained glass use. Putty will keep out the weather, but won't do enough to add strength to your panel. I like Miracle Mud best because it is easy to mix (you can control the consistency too) and since you can mix just what you need, you never waste any.
:Do I have to use whitening?
Actually, it is called "whiting" and is a calcium carbonate powder that is helpful in absorbing excess oils in your putty to help it set up, as well as acting as an abraisive to give the metal a nice finish and help in cleaning off excess cement from the glass and came.
I have heard of folks using sawdust instead of whiting because there is less danger from inhalation as well as less danger from lead abraision leading to poisioning, but I have never tried it myself.
:What do I do after the flux is washed off?
After the flux is washed off, let the panel dry for a while, then begin the cementing process using a bristle brush to force the cement under the cames. Sprinkle whiting over the panel and brush it around some, then let it set for a few minutes, them use a pointed stick to cut away the excess cement in close along the cames. Next add fresh whiting and brush. Repeat on the other side.
