What's best for preparing paper body tubes for a super-smooth finish?
Something to fill in the little spiral gap in the paper cover as well as
any low spots.  I'm sure a few coats of primer would do the job, but
that's a lot of sanding.  Is there anything like a thin, brushable
'bondo' that sands off easily?

Not just "like" Bondo...but *is* Bondo.  Try one of the
two products (they are actually the same thing, both being
made by the RPM Co.)

1)  Testor's (red) model filler-putty
(Found in any good hobby shop... *avoid* the WHITE
putty)

2)  Bondo (red) Glazing And Spot Putty
(Found in any good auto-supply store)

Thin these with lacquer thinner, or Testor's Liquid
Cement (the type in a bottle, for plastic models).
Thin to the cliched consistency of milk, or heavy
cream...and brush it on.  In my experience, the adhesion
tends to be a small tad better using the Testor's Liquid
Cement...but, you will get a lot more mileage with
the lacquer thinner.  There *will* be some shrinkage,
but this is minimal when applied in thin coats...and when
done this way, each coat is basically dry in 30 minutes.

Greg, that is some *great* advice!  I've been using the stuff for more years
than I care to mention but never thought of thinning it!

Thanks,
Dave

Funny...how often you hear that.  I guarantee...that once you then
it, you will be asking yourself: "How did I ever use this
stuff *without* thinning it?!"

:o)

I have a tube of this - Bondo brand - that I use with rockets.  I like
it 'cause it dries fast, and can be sanded in as little as 20 minutes.
I tend to only use it for last minute filling.  Otherwise, it's FNF and
then wait overnight before sanding.

That said, when I hear "Bondo" I still think of polyester body filler,
the pink stuff with the separate hardener.

It's kinda like Kleenex or Velcro.  The brand name is almost too
recognizable.

Elmer's Fill'n'Finish Wood Filler.

It is their normal wood spot filler, but with microballoons.
Thin it to slightly thinner than pancake batter consistency with water, then
paint it on to the tube.
Let dry then sand almost all of it off.

Easier to deal with than Bondo.
