Estes Laser Lance #3218, Part 3, Fin Prep & Seams

The fin grain was filled with CWF and primer/filler before gluing it all together.

Upper picture is the first CWF fill, below that the filler/primer after sanding.

Each fin is made up of four pieces.

The small piece is the center, front spacer.

I glued the front spacer hoping to avoid more filling of the joint. 

The top and bottom were evened up.

These tubes had very little seams. I still ran a pencil line in them to see it better. 

CWF was set in the seams and were sanded smooth after it dried.
