Jaegers 6" f/10 "GJD" OTA Construction - Main Tube (several coats of primer applied)
 

Main Tube hung primed - 4 (Click to see an enlarged image.) 

 
Making certain that the main tube was dust free, I applied three (3) coats of primer to the exterior of the main tube and allowed it to cure fully for 24 hours.
