Took a break from the crotch strap assembly and primed the push pull tubes. Cleaned the tubes inside and out with scotchbrite and Alumiprep. Rinsed with water and dried. Mixed up 8 oz of primer and sloshed the tubes for about a minute each. Since this stuff does not take long to dry I took the remaining primer and primed the outside of the tubes. Hung them between the tracks of the garage door with a hanger and let them dry. The inside cote is a bit thinner than what I sprayed on the outside.
