Hi Gang,
I found my rear-view mirror in a pile of junk, 40 years of weather made the steel rusty (cleaned by electrolyse and ready to be painted) but also the mirror part of the glass is mostly gone. I could cut a new one and polish/round off the sides, but mirrors nowadays aren’t as thick as the one I got and if I can keep it original for a bit more money I will.
Any hints? Do it myself?

Thanks
Richard
