Thanks for the comments, Marc, Joe, Brian, MKhoot, Mucker, Andy, Leon, Mustang10, mykroft and mfsob.
Joe and mfsob, the white scared me too but I had just completed a yellow trainer so I had some experience with a hard to paint colour. Unfortunately I tried to do this with one paint layer and got the area between the blisters too thick and lost some engraved detail.
mykroft, I only added some scratch detail to the blister guns and mounts as well as adding foil seat belts to the cockpit, though you can't see the belts very well.
