Well Tom this is a site about ol'timely cars. So I say cover it in motor old. It'll shine fine but be sticky for a couple weeks. Repeat as needed.

To be fair, people come here to know how to make a 35 taillight to work or whatever. There is plenty of sites dealing with 80s paint. Now if you were asking if I have lacquer original paint or urethane. I could say get a rag with mineral spirits and see if it wipes away in an area you can't see. but I don't think I need to fill my shoes with 85 crown vics at this point. Although I wouldn't mind having one!
Dan Aykroyd would say look for a state dept marquis/marauder.
