Semroc I.Q.S.Y. Tomahawk Build Part 10 Fin Prep

I decided to prime the fins off the model.

Because the primer seals the fins, the fillets wouldn't be as strong. So, a little masking was done done the root edge.

This mask would leave just less than 1/16" of raw wood above the root edge for the fillets to grab onto.

Here's the primer sprayed fins after the masking tape was removed. You can see the raw wood along the root edge.

When sanding the fins, stay away from the edge taper line. Concentrate on the flat areas of the fins, not the edges. If you sand the primer correctly, there should be some left at the start of the taper.

The primer that's left on the line will actually accentuate and sharpen the start of the taper.
