I have a question I hope it can be answered. Here it goes. I have a project coming up to do ghost flames on a 54 chevy pickup, I never airbrushed on a auto before. My problem is the owner painted the truck himself but did not clear coat the paint. now, I will be using createx transparent pearl for the flames. But not sure if I have to do a clear coat before my artwork can be done or can I paint right onto the existing painted area. I will be using wicked pearl waterbased paint. Any recommendations will be greatly helpful. A step by step explanation would be greatly appreciated.
