Personally I think the interior will look nice no matter how you elect to finish it: headliner, glossy paint, Zolatone.
I can testify that if you're going with a speckled finish, as I did, it's easy to get carried away and do WAY too much finish work before the paint goes on. Faux Zolatone hides blemishes like nobody's business, and blending in the areas around the doorway that are best left unpainted until after final trimming and sanding is easy - just have to take some care with masking and with heaviness of splatter application to keep the speckle density somewhat uniform. Hides repair areas very well.
You definitely want to do all you can on the inside of the lid while it's off the plane and on the bench. In my case, that philosophy included permanently affixing the doors as soon as the top was on the airframe so that pinhole filling could commence - with micro to level edges and fill pinholes, then neat epoxy wipe and lots of wet-sanding. The screws that hold my door hinges onto the top are buried never to be touched again, but the top was able to be finished to primer-ready while waiting for Cee Bailey to make my windows.
Transitions between the already painted areas and the fuselage structure still in AKZO are easily "Zolatoned' when the time comes and all the little transition fairings (cable chases, etc,) are fabricated and in place. As I said, the finish, which is latex house paint, stone-texture spray paint and clear spray enamel, is very forgiving and easy to apply. If you plan to finish the interior in a gloss epoxy, by all means spend the time getting all the blems out first. My two cents.
