Stupid is as stupid does! Think about it. A scratch is a certain width, when you polish it you are just grinding off the edges of the scratch and actually making it wider. So unless you are capable of removing all the surrounding material to the depth of the deepest part of the scratch AND maintaining the profile to within a very very small tolerance then this just WILL NOT work. Filling the scratch with wax cannot work either as wax does not have the same refractive index as the lens material.
