For fins, I'm in the "self-adhesive label paper" camp. Stick it on, trim, and hit the outer edges with thin CA to seal them down.
For NC's and transitions, Kilz primer is a good method. You will sand much of it off, but what remains becomes a really good "skin" that can be polished with progressively finer sanding papers before the color shot is applied.
For final finishing/decal seal coating I use "FFF", or what used to be called "Future Floor Finish". I think it's been renamed to Pledge, but it's still the same stuff. The technique has been around since the stuff first came out. I airbrush it straight, no thinning. Works both as a decal surface prep, and as a decal sealer.
FnF is still a good surfacer, if just a bit messier. It's water-based, so you have to be careful on thin fins to do both sides evenly, otherwise the fin will cup with the grain as one side expands and the other doesn't.
