Sorry, I know these topics have been beaten to death and trust me that I've read the other threads already, but please bear with me for a very specific question. I want Xpel Ultimate for the front and Opti-Coat Pro for the rest of the car. In my area, there are detailers that can do Xpel or Opti-Coat but I can't find anyone that does both. From what I understand, the ideal scenario would be to have paint correction, then Xpel for the front, then Opti-Coat for the rest of the car. Is there any harm in doing the Xpel for the front WITHOUT paint correction first? Obviously the Xpel installer will do a thorough cleaning and clay bar if needed. But is it worth the hassle to try to arrange for formal paint correction before the Xpel?
