It all depends on the purpose. I like Mr. Surfacer 1000 for finding bad seams and sanding flaws, it is a light gray and can be built up to fill small errors. White is good as an undercoat for colors which don’t cover well, particularly yellow or orange. A high-gloss black is good for metal finishes, or a flat black to emphasize shadows in cockpits or wheel wells. In any case, it has to sand well without leaving an edge where you sand through the primer.
Got me on this one; never heard of it. Can’t see any guns on either photo, only the dorsal turret. Why the Douglas version didn’t supersede the Boeing B-17; or why Boeing never incorporated the engines, or considered two 37mm guns in the B-17 for head on defense, will remain a mystery. Much wasted energy and money here.
Most of the time the XB-19 flew without the guns fitted, but if you look closely the 37 mm are visible in the dorsal and nose positions in the firs picture with camouflage. The XB-19 is roughly twice the size of the B-17 so there is also a scale issue. A 37 mm in the nose of the B-17 would have been intimidating, but experiments with even a 20 mm were found to be unworkable.
Did a bit of checking online; this birds wingspan was 73 ft longer than the B-29 (!) Since the working model (your camo pic) was flying after Pearl Harbor; though a “concept design”, I still wonder why they didn’t mass produce it instead of the much later B-29.
What the XB-19 brought to the table was great range. If England had fallen the design might have been developed further and/or the B-35 and B-36 programs would have been accelerated.
Jeff, during the war wasn’t this used to ferry folks back and for to the canal zone from Florida? I think there was a semi-regular run at one point. Not sure I realized that it got inlines at one point. Looks better with them.

Off topic Jeff… Is using white as a primer coat a good idea?

Merci Jeff. I don’t intend to start filling and sanding the Spitfire. I will go with a gray colored primer.

You’re thinking of the XB-15, which was similar in many respects. Both were huge and one-off designs.
