This paint was done in 2016 when it was in the body/paint/hotrod/MC shop lol, it's Summit Chassis black that I had plenty left over so told the guy shoot the dash but leave the dash top semi gloss and clear the front/face, well he never got around to sanding the clear and I pulled the car due to other reasons so now what's the best & cleanest way to finish it? sand and buff? Or spray bomb over it? Dumbazz paint shop got over spray on it too
