I primed each of the pieces of the tie down bracket assembly using an airbrush. As all the peices are small, it actually worked fairly well in my opinion and went faster and was easier to clean the setting up the whole environment to spray using the HVLP gun.
After the primer had dried. I rivetted the platenuts and spacers together as described in the plans. I then match drilled the aileron bellcrak mounting brackets. The entire assembly was then bolted to the wing spar as directed.
