CAREFUL!!  If that automotive primer gets through the pinholes wet, it can 
dissolve the styrene foam underneath with very disasterous results to your 
airfoil!.  Bob Chatman's suggestion to fill the pinholes by wiping on spackle 
(use a plastic artist's spatula/old credit card/scrap of balsa to force it 
into the holes) is a good one.  If you then follow with lacquer type primer 
(such as automotive or Krylon), mist it on so the spray is nearly dry when it 
hits the surface until the area is sealed.  Even safer, seal the area with a 
thin coat of epoxy and let cure before getting anywhere near it with primer 
or paint.
Good Lift!
