-Scrubbed all the vertical stabilizer parts down -SEM rattle can primer package showed up just in time from Fed Ex. Primed all the parts in two coats. Got to compare the primer I have been using (U-POL) against the SEM as I still had some U-POL left over. I think I like the SEM better. It appeared to cover and flow out a little better. I’ll see how it stands up to abuse when I start riveting. The U-POL self etching primer is available at my local auto-body paint supply store for about $25 for a big spray can. The SEM via mail order is about $22.50 a can. -Clecoed together the VS rear spar assembly. Got about 7 rivets squeezed before calling it a night
