There is no such things as best wax for a car. A good wax have not to be that expensive to be effective. I suggest you use liquid wax for your Honda rather than paste. Its easy to wax on and wax out the wax. You can wax once or twice a month depending on how you use your car. Waxing can be done in a cover place or garage.. Use also a detailer every time you clean your car. Its safe and it will bring out the shine in your car
