I have about 10 hours into the exterior of my wife's van, wash, Iron X, wash, clay, buffed a few scratches and the hood, machine polish, machine Klasse AIO, Klasse SG. In wiping off the AIO and SG I used some QD, mainly some Meguires QD I had around. I now read that you should only use an acrylic QD if you plan on layering Klasse (which I plan on doing). Did I screw up by using a regular QD? Can I still add layers? If not how do I correct this?
