Can I make a mirror on PET plastic using Tollen's reaction? I want to make a very shiny surface, like a mirror. I tried to use chrome paint but it's barely shiny. It's more like gray even though I bought one of the most expensive chrome looking paint. 

I know mirrors can be produced using Tollen's reagent on glass (seen some demonstrations on YouTube).

But glass is quite expensive for what I want - I would like to make the mirror on plastic - more specifically on PET - the same material that a normal Coca Cola bottle is made from. I have big sheets of this PET material and I intend to transform them into mirrors.

Will silver deposit on the PET as it does on glass?

I need to order the ingredients online, then wait for it a couple of days - also because they are quite large quantities, it will end up being quite expensive. So, before making a mistake, I thought to ask here.

Could I use a Tollen's reaction to make a mirror on plastic?
I found a video on YouTube making a mirror on PET bottles.

Just that it consumes quite a lot of substance, and is not using Tollens reagent. My question is specifically about Tollens reagent. 

What she uses is some "secret mixture" called RA-205. 

It just proves that Ag can precipitate on PET bottles, which further supports the fact that will work with Tollens reagent. I'm will edit this answer once I execute my experiment, so this finding may only be somewhat helpful.
