Query: Bad buy option to repair your glasses

I used this Armour Etch. It actually destroyed my expensive lenses from Lenscrafters. They cost me $350.00 . I followed the instructions and it also doesn't advise you to wear thick gloves. Your finger's skin will pill off. I used in other glasses too. They seemed to had reduced some of the scratches but its just a bad buy. It took so long to see clear. Cloudy glasses for a while. I bought a cleaner from Meijers store that they sell and that helped to repair them. Its kind of creamy tan lotion. Do not wasted your time. Save money and buy yourself a new glasses. Never used this product for optical glasses that are plastic type. I bet it would destroy just expensive sunglasses.
