Picked up the HS parts from the paint shop today and was able to begin assembly. I happen to live about 15 min from GLO Aircraft Painting at 52F so my process includes them using a Sherwin Williams Aerospace Epoxy Primer product (CM0483787) which is a light gray color.
Completed riveting the HS structure. Had to drill out one 4.0mm and one 3.2mm rivet that did not seat properly and redo. Ready to cleco on the skins and check for final alignment before riveting skins.
