Yes, I was referring to the actual mirror lenses. I've heard about the fingernail test on YouTube. None of the scratches are deep enough to catch a fingernail. I think I might try the Meguiar's Mirror Glaze unless you guys can think of something better. Thank you for the replies.
The Mirror Glaze line is simply a line of polishes. I would try a dedicated glass polish. The best woud be Car Pro's Ceriglass. You can get it online. Otherwise a paint compound/polish like Meguiars ultimate compound would be a great choice.
DO NOT USE PLASTIC POLISH TO REMOVE SCRATCHES FROM MIRRORS!
I learned the hard way.
Plastic polish is designed to remove scratches from uncoated plastic - mainly clear bare plastic. Plastic mirror lenses have a coating on the plastic to make them reflective. The plastic polish does not react with the coating the same way it reacts with bare plastic - it has a tendency to remove the coating! I am going to have to replace at least one mirror lens if not both of them. Take this information and use it to your advantage.
