is it okay to wax a car in cold weather?
 

is it bad to wax a car in these days??
its like 20-30F in my town..

You can do it ,as long as the wax is approved for cold weather. I dont know of which wax is though. Most waxes say not to use under 50 degrees. If you apply the wax you may not be able to remove it, unless you use it in a heated garage space.

Yeah, it all depends what the directions say. The wax / sealant we use can be applied in any temperature, including the hottest of days in direct sunlight.

If you do decide to wax the car, do it in a warm environment (ie garage).
