sq2278, Yes..this is my own company! I'm in Ontario, Canada! So I know what winter is all about as well...arghhhh!
The winter prep form is a great idea. I do the same! And I offer my regular customers a discount in price for just a wash and basic cleanup during those winter months! As you know..once they drive away in the winter, the car is filthy again...lol It's even harder for me because I'm mobile and work on their property and most times out in the open. Brrrrrrr....chilly....lol
