Winter in setting in hear on Colorado and I have prepped my car with a couple of coats of wax. I have only hand washed this car (baught used last March) but winter will send me to the car wash.
The question I have is will those high pressure wand sprayers blow the wax off the car? What other suggestions might you have for winter washings?

If you have to use one keep it as far away from the paint as possible.

 

i dont think it will blast it all off but yeah it will degrade the life of your wax and by the winter im sure there will be none left. just dont spray real close to the car and you should be alright. if u get a half way "warm" day during the winter i would give it a quick coat of wax just to play it on the safe side.
