Gold class wax is a show car wax. It gives excellent gloss but little durability. It may last 1-2 months at max. But it can be layered and applied frequently. It has NO abrasives in it.
Cleaner wax is sort of an AIO. It has mild abrasives, polishing effect with cleaning and added gloss. But yet again the durability is less. I wound not recommend using cleaner waxes more than 2 times a month.
But Gold class wax can be applied as much you like.
If you want other better options. then try Soft-99 waxes. They are amazing and cheaper than meguiars.
