Estes Sandpiper, Kit #1389, Part 5, Filling The Balsa & 3D Nose Cone

After brushing on CWF and sanding smooth, 

thin strips of masking tape were set on all the edges that were to get glue.

The fins and "wings" were taped down to scrap cardboard for a filler/primer spray.

After drying, the filler/primer was sanded to surface filling any remaining grain line.

Here's the tail cone - 

The tube seams and tube/tail cone joint got a line of CWF and sanding.

Filler/primer spray followed.

Here's the tail cone and low end of the body tube.

That black line at the joint isn't a gap, it's the printed cut line of the shroud border.

The plastic ridges on the 3d nose cone were initially sanded with 320, then 400 grit. This removed most of the print ridges. 

This shows the nose cone after the filler/primer was sanded. There are still some shallow ridges. It'll take another shot of filler/primer and more sanding to get it smooth.
