Kevin,
Sound good, just be careful with the Flex-all. You didn't mention the brand of dope but if it is Brodak it was formulated with the plasticizer so just a touch is ok but to much and it will dry with a softer surface that will make it harder to rub out. Also, are you going to put "death paint" over the clear? If so I would go real easy on the Flex-all as you don't want to have adhesion problems.
WTW the ship looks great. What are you powering it with and what does it weigh?
Best, Dennis Toth
