I joined the forum because I have two vintage Mexican calendars that I would like to frame but sadly, they are not in the best condition. I've asked several professionals both in USA and Mexico for their restoration services and even though I know it would be the best path, I just don't have the money to go that route and the calendars are not that valuable themselves. 

The calendars photos can be seen here: Imgur: The magic of the Internet. They are lithographs and the material is paper (I don't know which type), sizes are: Sleeping woman: 22.5x18 in and Cigarros El Águila: 39x23.5 in.

I've done some research and I think the best course of action would be the wet cleaning/de-acidification, backing, filling holes and missing edges and retouching. 

I found this great post by Charlie detailing the cleaning process: Wet Work - Washing, Deacidification & Bleaching — The Vintage Movie Posters Forum but I have still some questions that I hope you could help me with:

1: Concentrations of the solutions used for cleaning (I understand that some people might not be comfortable giving that information if they have a restoration/conservation business, but an approximate concentration would be appreciated)
2: Is it indispensable to buffer the wheatpaste with calcium carbonate?
3: What kind of paper is used for the backing? I understand that the paper can be a Japanese rice paper and then an acid-free cotton paper but I haven't been able to find that type of paper.
4: Can I do the backing without a stretcher or do I have to make my own?
5: What material is used for the fillings? I've seen some people using gesso or paperpaste but I'd like to hear your thoughts. 
6: The retouching with thick paint would be a no go, since it would be too noticeable, so I was thinking on using watercolour pencils. 

I haven't tried to restore anything before and any advice would be appreciated. Please notify me if this violates any rule. 

I appreciate any insight and thanks for reading.
