New Way Letter - Go Build, Part 6, Filler/Primer On The Fins

The fins are plywood and don't require CWF filling used with deeper balsa grain.

Here I've taped down the fins over the fin tabs, keeping he filler off the wood for a better glue bond.

Here's a fin after spraying with filler/primer.

Note the tab and root edges didn't get sprayed.

After sanding,

there is some filler/primer left and filling the slight wood recesses.

There were a few deeper slivers that needed a bit of CWF and sanding to smooth out.
