70+ Camaro Sport Mirror Glass ????

[CamarosRus]

1) Is there anything that can be done to diminish the scratches in date coded
side view mirror glass, before you polish thru the refective silver mirror finish

2) If I buy new replacement glass with NO date codes I lose Originality Points
If my glass is too scratched I lose Condition Points

3) Pic below shows date code of Jan 1970 (1 - DMI - 0)
I have other 70+ Camaro Sport Mirrors where the right
hand number is 9 and one that is 8......Was this same
glass used in earlier Chrome Mirrors as I can undertsand
why the 8 (1968) Year Code

The silvering is on the back side. Polish with a glass polishing kit, cerium oxide, but stay away from the date code, that etching will get wiped off. Maybe a small piece of Gorilla Duct tape over the date etch to protect it.
