GM Special Lubricant High Temperature: application for lenses

I maintained the Юпитер-3 (Jupiter-3) 50/1.5 lens with applying GM Special Lubricant High Temperature (12345879).

There were some doubts about very cold weather handling. But this winter I shot outside with this lens and the focusing was still quite smooth. And the smell of grease has almost disappeared. So I will continue to use this lubricant in lenses.
