If you have any water spots on the paint, it is not a good idea to seal them in with a wax like Epic. A QD like Slick will help remove them, but not completely.
If you are only going to wash, then wax, do this. Wash, rinse the roof, then dry it,do the same to the bonnet, then one side at a time, then the boot. This way the rinse water will not sit on the paint and dry, leaving spots.
But as has been said already, start using clay before you wax, the results will be way better, both in how the end result looks, but also feels.
