I like to spray Dura Lube Advanced All Purpose Lubricant Protector in the
lock and handle areas.

I live in Chicago and it seems to work fine in the vehicles that I have used
it on. ;-)
Oh and BTW it seems to last too!
One bad thing is that I can't seem to find it anymore in the usual local
places. :-(

JMHO.
