I have had lens CLEANING in the past , with toothpaste , scrubbing-sanding , and polished/buffed with unknown chemicals.
They have been a TEMPORARY fix.
The reason I am HOPEFUL that this is different, since there is no real effort to REMOVE any surface damage, but rather, just to Polish it.
AND ... even if it DOES return , ZEP is plentiful , and it only takes 30 seconds to apply 2-3 coats and redo the process, so I am game for that .
