  Scott,
  
  Micro is really hard to feather out flat over the softer primer or even the
  wing skin.  I tried and it never was really straight.  Every batch of  micro
  has a different hardness so they sand differently.  I ended up using  micro
to
  get it close and used some lightweight body filler for the last little  bit,
  never more than maybe 1/32" thick.  So the micro gets the shape, the  body
  filler blends the micro to the skin, and the primer gets it very  straight.
  
  I always wet out the wing surface before applying the micro.  I  painted the
  pure epoxy beyond the micro fill area by a few inches to create a  barrier 
to
  protect the wing skin.  Thick micro is really hard to spread  thin and
feather
  over the low area.  Thin micro is easy to spread but a  pain to sand.  I
  mixed the micro really dry, so dry that it was  almost impossible to spread.
  I
  held a heat gun in one had and the spreader  in the other, warmed up the
micro
  so it would spread.  [another trick is to cover the micro with a sheet of 
peel ply before smoothing... it keeps the micro from being dragged around when 
you trowel it.]
  
  The WLS tends to dry with a semi-glossy surface.  Even after sanding,  it's
  still glossy in the low areas that you want to fill.  I took a piece  of 80
  grit and roughed up the remaining glossy areas before using filler or 
 micro.
  
  I would say that I finally got relatively good at body work about the time 
 I
  was done!
