Collodion tintype

I've been looking through Youtube searching alternative photography and find there are hundreds of posts about tintypes, transfers, collodion, Daguerreotypes, and much more. This one caught my eye though, as it looks pretty easy to do and a lot of fun. I doubt you really have to make a mess like this one shows to be successful, but it may be inevitable. Here is a link to more on collodion, including some big ones. Another site, Scully and Osterman, I've pointed to in the past and is quite relevant here.
