You can apply right away, that rule doesn't apply to new vehicles.
However, if you had body work done on your vehicle and it went to an autobody shop and had a panel painted, it's always best to wait a minimum of 30 days for your paint to cure. The only exception is if your body shop used infrared lighting to bake the paint, very few body shops use this method so if they used the typical ovens to bake the paint, then it's best to wait at least 30 days before applying anything.
It's not the ingredients in the products, but more has to do with allowing the paint to breathe and expel the gasses, so it can fully harden and cure.
If you apply our products such as our Liquid Wax and Hybrid Wax, it seals the paint and prevents the gasses from releasing, which may cause problems down the road with the paint.
