Thanks Baxster and Lufbery. I was pretty pleased with the outcome. The new owner is enjoying his Falcon. I'll start on my own very soon.
As for the blast marks they were done with pastel chalks. The one by the radar dish was done with no gouging of the plastic at all, unlike the big one on the cockpit side.
Give me a few days and I'll wirite up a little "How To" on my pastel blast marks, along with pictures.
