First and foremost, thank you Dan for taking the time to respond to my questions! I've been super busy but I read your comment Wednesday night and I appreciate the quick and detailed response!
After reading your suggestions I used the remaining Graphene Ceramic Coating on a bright metallic green-yellow vehicle (known as Green With Envy or Mojito) and I am VERY glad I had the UV light! I couldn't tell where I was putting the coating. I had to work in a dimly lit garage and use the UV light the entire time. But I did as you suggested: break panels into smaller sections, do a perimeter, then lay down the coating. I added more coating to the applicator when I changed directions (horizontal vs vertical). As soon as I was done crosshatching I immediately started gently wiping the coating because it dried very quickly. Overall there are a few high spots but they are VERY difficult to find unless specifically looking at them, this green hides imperfections very well (even scratches).
So today I tried the first car again. I used a machine and recompound and polish to remove the old coating. But I did the same processes I did on the green vehicle and ddaannnnggggg did it come out good! I wish I would have broken up the doors into 1/3s as there are a few high spots but I can live with it. Again the Graphene Ceramic Coating cures almost immediately but I'm very happy with the overall results!
Attached is a picture from today. You can see how evenly the coating appears on the quarter panel (I wasn't using the UV light while applying). For reference the door has zero ceramic coating on it. Next weekend is a white vehicle with heavy swirl marks, it will be fun and interesting to see how good everything comes out!
