I purchased a Peacock silvering kit last year for the Telescope Optics
Workshop for a silvering demonstration.  The kit is very expensive! 
However it is inexpensive when you think about what you get, enough silver
to cover the Palomar mirror!!!   It was easy to make up a coating, if you
are
meticulous, and have very very clean habits in handling chemicals.  After
the demonstration, I split up the kit into 3 parts and sold it off, so
sorry dont have any to share or sell.  I would suggest that several ATM's
get together for a such a project.  I dont believe the coatings are as
smooth as aluminum deposition, however, maybe someone who has done some
testing can clarify how accurate the coatings are compared to
aluminization.
