Re: ATM Coating Silver?

Hi Michael,

>>>
    I  am about to finish polishing and after inquiring about aluminium
coating
here in  Brisbane ($380 for 10"!!) I am looking at doing a silver coat
instead.
My  question is, Can the protective coatings they use on aluminium be put
over the  silver as I assume it is not an electrically driven process in
a vacuum  chamber?
<<<

In France a company proposes also protected silver. Done in vacuum
as for standard Al, as far as I know.
I recently *heard* however that the longevity is quite shorter than std
aluminium.
And, in any case all their coatings are horribly expensive! On the other
hand,
even here in Europe $380 to coat a 10" seems much!

Frédéric, do you wish to comment further?
