3 Coats of Pactra Aero Gloss Balsa Fillercoat followed by 2 coats of Pactra Aero Gloss Sanding Sealer.

I would vote for this as a preferred method. I like the way Balsa Fillercoat gets "sucked into" 40-50 year old balsa .... but have to admit lately I have been leaving out the two coats of Sanding Sealer and been using a coat of filler primer instead.

My preferred method has evolved over the years - and the exact method depends on how good the final result needs to be (e.g. display model vs. a frequent flyer). However I'm anal enough about it that I always do at least basic wood sealing and filling body tube spirals even for 'disposable' flyers.
My current primary method is a layer of Elmer's white glue (i.e. "Glue All"), sand, then a coat of thinned Elmer's Wood Filler, sand, then at least two coats of sandable primer (different colors). I like Krylon Industrial Tough Coat sandable primer.

I only fill tube spirals on Scale jobs and even those not often.
Wayyyyyy too much tedium.

I said I'm sort of anal about it. There have been times when I was building a simple rocket for some public launch (and didn't even expect to get it back after it flew) and I still couldn't stand not filling the fins and body seams...
Yea, I know, but it's sort of 'if it's worth doing, it's worth doing right'.

Quick and easy method for sure, and a shortcut that many modelers use, but makes for a heavy rocket with the resulting performance penalty.

So far, 25% have selected "other". How about posting a comment and letting us know what
works for you?

Rob, check the archives/posts here., this has been tossed around forever.

I usually use diluted Elmers wood filler but it depends on the situation. I have a Enerjet Hustler clone with it's long two piece fins that I used epoxy to fill and strengthen.

But to the point of the poll my preferred method is EWF since it is very easy to sand and doesn't react to any paint I've found yet.
