Estes Antar #7310 Build, Part 8, Filler/Primer & Fin Marking Guide

Whoa, that's a lot of balsa! I was building four kits.

This is right after shooting the CWF filled balsa with Duplicolor Filler/Primer. 

This was pretty good balsa, the filler/primer didn't need much sanding.

Look close and you can almost see the slot fill lines.

The provided fin marking guide matched up perfectly! 

On the right I've sanded the filler/primer down the fin root edge lines for better adhesion. Sand off the primer to the body tube surface. There is no need to sand into the tube. Sand until you see the brown tube peeking through the gray paint. 

TIP: Round off the corners on the assembly jig where it could contact a fin fillet.
