I put wax on my car every other month and I use Mothers Wax. The frequency you wax and polish depends on the weather elements in your area. If it rains a lot, I would recommend you to wax and polish often.
You can wax and polish it as often as you like. However unless you want a ton of fine scratches then you need to make sure the car is completely spotless. Also use a micro fiber cloth pad and and a high quality polishing compound in an adjustable speed buffer.
