Local Pressure washer wax question.

So I went and cleaned my baby with a full rinse then soap and then rinse again and then used the wax from the pressure washer on my car and then used the final rinse(so called anti wet spot spray) as a final coat. Anyways my car looked cleaner then ever, my question is, how often is it okay to use that wax spray on my stang without it causing damage? Clearly it’s not amazing wax or anything but it let her shine in the winter for more then 10 minutes.
