Just a short visit to the hangar to prime the inside of the three flight control push tubes. Pretty easy process after the tubes are prepped and one end is taped over. I mixed some acid based primer, about 3/4 cup (which was too much.) Then slowly pour in the open end of the tube and swirl around. I went through the process twice for each tube. They are now drying at the hangar, ready for the end bearings to be mounted.
