I recently asked a question on the POCA web board what could be used to polish grimed up, dirty scratched lenses. After several suggestions, I used toothpaste to smooth them out and then the same buffing compound I used when I buffed the paint out. Used a high speed buffer set on 3. They came out looking new. Here they are before & after. Since I can't post any pictures on the web board, they are posted here.
