I have some good friends that live up north (arctic circle) and I brought them some stuff. The ambient temp was -45C, but travelling on the sled (60-110mph) the wind chill brought them down... A lot. Everything froze solid. Like some soap, APC, wax (solid already lol), tire dressing.
Not to argue but wind chill only effects living creatures. Your soap, APC, WAX etc cold be in 3000mph winds and it wont ever get colder than the ambient temperature.
