I think I'm starting to agree with Silverfox and may stop waxing. I have a black tacoma which is a dd and I sealed it with WG3. Several weeks of normal driving with rain here and there. After a good wash, everything was fine. Then I applied fuzion and it looked great. Same dd routine, but after this wash etched waterspots everywhere. I'm still new to all this. Could the wax be the cause? Can their be etched waterspots that are not down to the clearcoat. I mean could the spots be in the sacrificial layers and my cc is safe? What do you guys think? Thanks for your help.
