I finially got prime the tailcone parts (apart from the skins), at least one side. As you can see in the pictures I did not use the green aviation zinc phosphate primer for these, I decided to use a grey primer for the inside of the forward and aft fuselage since these will be visible from the cockpit (Thanks to Jim Lewis for the idea). The grey primer is a killrust metal etch primer from the local hardware store. It is much easier to apply than the aviation primer, I use a spray gun, and it looks very nice by itself, this saves me having to paint the cockpit afterwards. After priming I formed one more turtledeck former over the formblock, I have 4 finished now.
