Homebrew PCBs

A youtube video shows plating surfaces using silver nitrate, ammonia, sugar,
and sodium hydroxide.  Will this work for via plating or would the silver
rub off too easily?  The video description says "thin layers of silver can
be wiped off with a cloth if the silver goes where you don't want it.
Thicker layers can be removed by applying hydrochloric acid."  If it could
work, a big positive is it does not require hole activation and thus have no
limit on hole/via diameter.

I'd be interested in some details on how you are going to do the through
hole plating.

Thanks

Oh someone wanted to know what am I plating?

I was going to plate my drilled out hole with copper so that on double sided
PC, i'm not having to stick a piece of wire and solder both top and bottom
copper.

You could also use it to plate tin if you want. But your plating solution
would have to be different.

And minor correction At 5 Amp you can plate 6"x6" double sided PCB not
6"x12"
