Interesting. Not sure any of those chemicals are available here in the states, and where I'm located, there's no hazardous materials disposal sites either so keeping the unused or waste material is problematic. Lastly, this is obviously a labor of love for a dedicated restorer. For most, I would venture to guess it's far to much work. Also, I think the guy has done a lot of trial and error. So while he made it look quite easy (albeit a ton of work), a newbie would have to go through that same learning curve and process.
