Ok so I'm about to apply some Poli-Coat and Collinite 845. My question is normally when I was my truck, being that it's black. I have a lot of water spots. So I usually just go over it after I dry with a quick detailer spray, which cleans them up. Can I/Should I do that before I apply my sealant/wax or will that not be necessary when I just apply Poli-Coat?
