Do you "rework" your lenses when you encounter problems such as: swirls, poor coatings, prism, scratches, thicknesses, waves/abberations, etc? If so, what do you consider to be your success rate? IOW, do you feel it is worth the time and labor to attempt to "fix" a lens? Or, do you find most attempts result in other problems such as off power, etc.
Any comments or experience would be appreciated.
