Hello all!
I was hoping to pick your brains as I have found nothing in my own research.  One of my projects consists of a mirrored dome.  Now I have found how to do this to glass, but as I am not gifted in the grace department, I will definitely break it. Therefore I would like to figure out how to do this to plastic.  The look I am going for is as close to the mirror coating effect on sunglasses as possible.  Any ideas?

And if anyone is interested, here is the link for mirror coating glass:

I just realized that there is a vital fact missing in my request.  Like the sunglasses I would like the plastic coating to be one-way or x-ray mirror coating.  Heh, if it didn't need that little aspect, then spray paint would have been an easy solution.  But no, I like to make things a complicated.  Wink

Politely curious but can you provide some specifications as to the size of said dome ?    Blindly leaping here but check the links below.

The dome I can construct myself with no problems.  It will be about 16"x10" and about 7" in the center.

If I can't find someway to do it myself, I may just have to take it to a automotive window tinting shop as there are mirrored tints for car windows.  I have heard it is a bit tricky to do that properly on your own.

Getting an even coating of paint or tint on a curved surface is a chore , the exception being when such is masked and only needs partial coloring.

Best of luck with your project !

Most auto-window tinting I have seen is done with a film, so I am not sure how it will sit on a domed surface. Most mirror-finish films I have worked with have been polyester-based, and not particularly stretchy.
As I recall, most of the mirrored plastics I have seen were done by deposition of a metallic layer under vacuum conditions, which may prove tricky at home—I can't say impossible, as odds are, someone within a ten-mile radius of my house has built his or her own vapor-deposition rig, in the garage, from surplus printer parts and a microwave oven, or something, and will display it next month at Maker Faire.
