How do you keep wax on a car?

[mustang5.0lx]

if you use a good wax the wax will not come off next time you wash your car use car soap and it won't take off the wax the only soap that takes off wax is if you use dish soap you should wax your car onnec a month i usually do it more depends on the weather i recommend try the emerald series from turtle wax it carnuba wax it works the best for the price its hard to get off thats how you can tell its a better wax if you cut it then use a circular motion it comes off easier
