Question about Poly Watch Plastic Polish

The paste is not suitable for mineral glass. And even if it is, it can't remove deep scratches anyway.

I agree with the previous answer. To remove deep scratches, the glass must be polished down to the deepest point, which is correspondingly intensive. However, I was able to polish a larger scratch to a point where it was less noticeable.
Deep scratches on plastic lenses also need a lot of patience and above all pressure.

Light scratches yes, deep scratches unfortunately no. 🤘

This product is intended for plastic or acrylic glass and for very light scratches, so no. You need to change the mineral glass, that's all. You just need to change the mineral glass.
