I charged a local fellow $120.00 for his. The paint is expensive. Just the color, WB, was $150.00 for a pint. PPG Deltron. None of those cheap paints.
Add reducer and catalyst to that and your looking at $250+ just for the color.
Plus an adhesion promoter and a flexative and don't forget clear/catalyst/reducer coat on top of that.
The bitterness of poor quality remains long after the sweetness of low price is forgotten.
