Had to prime the spar where I cut the countersinks. Don't want any nasty problems down the road! Anyway, I taped off the spar flanges top and bottom on both wings and hit it with the 7220 primer. Quick n easy.
Taped off and ready to prime. Note the grey primer from the fuel tank nutplates already on there.
Finished - if the spar looks like it's sagging it probably is. I have to get everything re-leveled.
