The doors look great Dave. I would put more than 3 coats of clear if your gonna use the balsa wood to wet sand it down. I put 4 coats over the car, 2 over the stripes, let it set for week, blocked it with the balsa with 1000k, put 2 more coats ove the stripes, then 2 more over the whole car. then hit it the balsa with 1000k, then 1500k. then buffed the car out.
