Primer

With the Saturday morning garage sale done with for the year there were adequate conditions (not breezy or too hot) to protect the V-stab skeleton by spraying it with primer.  I put enough scratches in the spar that I feel better coating it before the AlClad skin goes on and the skeleton is out of sight forever (one hopes).  The only self-etching primer the local NAPA store carries is DAP 1690.  DAP 1690 is kind of an olive drab except uglier, if such a thing is possible.  The stuff costs $10 a can and coating the V-stab skeleton took about one and 1/2 cans.

  
Hung the V-stab skeleton from a string to spray it with the rattle-can.  It's rather flimsy until it gets its skin rivted on, but very light.

Notice the color on the cap is nowhere close to the color of the actual primer?  Before priming I cleaned the V-stab skeleton with NAPA 7234 Automotive Prep Clean, which is a spray-on wipe-off cleaning solvent, and let it dry for a couple hours.
