There's a tight corner on the upper fins, right where the breaks happened earlier.
I dropped a little more CWF in the tight corner than normal. It might end up a little rounded after sanding.
Sandpaper was folded and most of the CWF was taken off.
Sand carefully, you don't want to break these.
Here's all the fins taped down on cardboard for a shot of primer/filler.
Notice I've taped the fins down with all the root edges facing away.
When sprayed from this angle, this will help keep the primer off the root edges. Less sanding and a better glue joint.
The launch lug is cut in two.
After filling with CWF and sanding, set the lug over a dowel for cutting.
If you try to cut a lug without support inside, chances are it'll be crushed.
