Whats the coldest you ever washed and waxed your car?
 

I wont wash my car if it's 50 or below and I wont wax it if it's below 60. I've seen some people wax their cars when it was like 50-55 out and you could see all of the streaks and dried on wax. Looked horrible.

I've washed it below freezing before, using a self wash with heated water.
