The filling should turn out very well.
As always -
I sand off the laser cutting ash also removing the hold-down tics.
The inset picture shows the upper arm of the wing fins.
Laser cutting is not perfectly square but flares out at the bottom side.
Carefully sand and square up the edges but without changing their shape for a better fit.
The square tubes don't have concave seams. There are layer overlaps about 3/32" wide.
I sand these down with some 220 on a block. Later on, filler/primer should take care of any roughness after sanding with 400 grit.
The square launch lugs have a definite seam.
Brush on some CWF filler and sand with 400 grit.
The CWF stays in the indent seams.
On the right side is a before and after sanding.
