Sinlge stage or 2 stage paint

I shot alot of metallic paint in another life, so I vote base / clear. I like single for all but exterior panels. Exterior, I like clear 'cause it is more forgiving if there are a few imperfections in it and buffing now and in the future with follow up buffing or repairs.

Like for a driver you will end up with scratches and miscellaneous stuff happens over time, you can repair, blend, buff all sorts of things more easily with clear. My two cents.
