Just washed an old metallic silver Honda hatchback for the first time since I got it 6 years ago. Most of the paint will polish out nicely but the roof paint is pretty dull. I'll try polishing it first but if it's anything like similar cars, that wont help much with the shine. I have some of this 2K clear coat I've been wanting to try, https://car-rep.com/us/product/car-rep-2k-polyurethane-clear-coat-high-gloss-11oz/ Would it be worth a shot? I noticed while washing it, the roof looked nice and shiny while wet. Wouldn't the clear coat give the same effect?
