While it is true that many new(er) types will not tolerate frost on the wings (polished or not), many older types (DC-3, as an example) can be flown quite safely with well-polished frost.
As for frost on the underside of wings on jet aircraft, B707's (again, as an example) had no restrictions whatsoever in this regard, so a few youngsters who, having never flown older types, will more than likely be unaware.
What about the big......Aaaaah Lockheed?
