Estes Aries SST, #1927, Build, Part 5, Fin Grain Filling

The balsa pieces and launch lug were first filled with CWF and sanded to surface using 400 grit.

All pieces were taped down to cardboard for some spraying with filler/primer.

While the filler/primer was still wet, you can see the remaining balsa grain that should disappear after sanding.

I still had a few small spots where the grain was deep.

Some CWF was pressed on using a finger.

The pic on the right side shows the same wing after sanding to surface. The balsa is filled and sealed.
