I countersunk, Alumiprep'd, Alodined and primed the underside of the canopy rails ready for final riveting to the airframe. I then added some JB Weld to the area that had been creased by the shrinker. When this sets, I'll sand it back smooth and re-Alodine and prime the area ready for final paint. After that, I Prepsol'd the upper longerons and inner skins and primed or re-primed where necessary.
