Scratch Repair?

[marcingo]

Sorry I wasnt sure where to put this question.

Has anyone heard of scratch removal on glass- I know when I used to watch late night infomercials they had stuff that would repair scratches on glass lenses (for eyes). Then I typed in glass scratch removal on google and it said there is a product however Im not too sure how well it works and whether its reef safe (it says it becomes activated with water). Other than that anyone heard of a way to fix minor scratches in glass

By the way the latter product claimed it could fix scratches on any glass including tempered.

Any thoughts
