If you need serious paint work and your in PA there is only one shop...Karosserie. They are one of the best in the WORLD let alone PA or the US. They used to handle all of Ferrari's paint work in the US (all cars that came into the US with paint imperfections would go to them). Back in the late 80's we had a BMWCCA meeting there and the cars in there for repair at one time blew my mind (4 Lamborghinis, 8 Ferraris, dozens of BMWs, Porsches...) They have painted a few of my cars and the work is flawless!
