Here in the "Magic Garage", on te West coast of Florida. I've used Johnsons paste wax for twenty years.
The only problem I've ever had was when the Air conditioner Drip pan leaked through the ceiling in the garage, while I was away on a business trip.
Sitting water on my tools for the week I was gone caused some rust, but I was able to cleaneup most of it, only leaving a couple of stains.
