Today I used the Duplicolor DAP1690 self-etching primer to corrosion proof the interior of the ailerons. Scuffed the surfaces with Scotch Brite pads and then washed with Dawn dishwashing detergent and rinsed clean (as recommended by many RV builders). Had to wait for the outside temperature to creep up to about 65F. Primer goes on easily and covers well. I then laid out the parts in their inboard > outboard order to verify nothing gets mixed up!
