I recommend these waxes:
All specially blended waxes that you will not regret purchasing them. If you are serious about taking care of your vehicle take these into consideration! I usually apply wax once a month. But with these you seriously do not need to for about 6 to 8 weeks.
I use these for all my clients and for my cars and everyone who has seen them in person and used them love it.
If you are looking to save some money though go with the p21S.
