? for Paint experts...

Unless the whole was repainted at that time, a spot in the engine compartment or trunk will not give you a true answer. I'd recomend taking a piece of 2000grit paper and lightly sand the bottom of the quarter panel or front valance. Like said before, if it sands white it was clear coated, then you could wetsand,2000-2500grit, and buff the car. It will take longer with the finer grits, but if you don't know how many coats of clear were applied, you will have less chance of sanding or buffing thru......
