I live in New Jersey in with for the past week it has been under 10° at best. In Hackensack there is a spotless tunnel that does the waterjet thing and I figured it would get dry on the way out being that they have 2 10 hp Baldor motors blowing air at the cars for 60 seconds.this really didn't matter because the water that was blown immediately turned to ice pellets and the rest froze solid onto the car!
In terms of keeping my fingers warm I use a 2 pair method where I keep one pair on the – windshield defroster vents to heat the fingertips up and the other pair I have my hands till they freeze up. While doing this I always make sure the gloves are not too furry, not too clingy, your bare hand doesn't let stuff stick to it obviously but the wool or cotton fabric on most gloves can be particle magnets that end up transferring to the microfiber....in addition to this I use the "Hot Hands" handwarmers you can find at a Blowes or the Borg for $7
Sort of unrelated to this thread I have found that some products will work in sub freezing temperatures These have been the more Carnauba based stuff. So Far I've had the best luck with P 21S Carnauba paste wax although I must mention the other day I had applied a coating of Menzerna Power Lock The roof of my car...well, it was so cold I got back in my car and forgot that I had applied it… The following day it snowed about an inch. The day after that I was parked in a parking garage at the mall and noticed product spread all over the roof and realized it had been on there for two freezing days...I quickly got a microfiber towel out of the back and it came right off and this is just a testament to what I believed to be Menzernas flagship product.
I would love to hear anybody else's input on product that works in the cold.
