Please complete this tintype formula for me:

I'm basing the following questions on the video on National Geographic's
website.
http://magma.nationalgeographic.com/ngm/bestvintage/multimedia_vid2.html

Sensitizer: Silver nitrate (what dilution?)
Developer: ???
Stop: Water (2 baths?)
Fix: Potassium Cyanide (4%?)
Varnish: (???)

What is the process of plate preparation (I've read they should be painted
black first and then sensitized?) and what metal is best to use?

Thanks,
Jon
