Almost done with my first BG, a Semroc Swift. Do you usually apply sanding sealer to the wing and stab?

I would use wood filler to fill the grain before applying sanding sealer. That will reduce the volume of the pores filled by the sanding sealer. I expect it will come out lighter that way.

Go light. I'd go with a spray dope like Deft Sanding Sealer and skip the heavy wood filler.

Free flight hand launch glider guys are still using dope...
"Building the Dynomite went quicker than the Maxima 30 which had a built up wing while the Dynomite wing is solid balsa and comes tapered. In addition there are more aspects of the Dynomite kit that are already done for you like in the front of the fuselage which comes with the DT built into the fuselage. Part of the boom pivot is also completed. This model cants the wing and the stab slightly a technique the video brought out. I finished the model with clear dope and spray paint as shown in the video." (http://scienceguyorg.blogspot.com/2016/05/dynomite-tip-launch-free-flight-glider.html)
or Helmsman Spar Urethane as described the "Finish" chapter here: https://amaglider.com/?p=view&a=stan-buddenbohm-general-catapult

Thanks everyone for the advice.
Interesting stuff. They also make a compound that works with fiberglass. I have order both. I really appreciate the suggestion.

Except for the color, they are the same thing.
Thanks. Hard to determine on my cell.

Is that the same as this stuff?

I used to have something like that that I thought was sold by Great Planes. Got rid of all my model airplane building stuff 20 years ago.
