Another detail crossed off the list! I ordered a set of pre-cut vinly N numbers from Aircraft Spruce. The day finally came to put them on, it went fairly well, it definitely looks great at 20 feet ;-) I opted for the 12 letters because some day soon I want to fly from my home in Midland, Texas to Alaska. 12 inch registration numbers are required in Canada, so... to avoid being shot down by the Canuts while traveling to Alaska I put on the larger size required for international flight.
