The nose cone is a new item from Apogee so the molds are new. There was very little molding seam to fill.
I got out my Dollar Tree store bottle of Super Glue. They are usually 2 for $1.00. It's medium thickness.
On the left you can see the slight seam left after sanding.
On the right is the raised bead of Super Glue. Apply enough so the bead of glue will end up a little higher than the surface of the nose cone. Do one side at a time and let the first side dry facing up and horizontally. Be careful, the glue can run!
The glue dries hard and clear. I used a diamond file to knock down the bulk of the bead. 220 grit followed then 400 grit.
On the right is the finished fill ready for grey filler/primer.
