With that done it is time to paint. I tapped off everything. I covered the helicopter with plastic. I covered the Model-T with plastic. I covered the whole RV-7A. I taped off the fwd top skin so I could spray it. I also removed the canopy and taped it off so I could repaint the front. Recall the edget got damaged in all the removals.
I primed the bare aluminum with green chromate, but no photos of that. Then I primed with sandable primer. Sandable primer helps hid the putty.
I used my new (used) 5 HP Jenny gas compressor. It has a 17 gallon tank. It worked great. I installed a painting filter at the gun handle.
