larry, this is roger mitchell, I work at TWA-AA overhaul in KC Mo, when we do 
composit repairs we use a perferated plastic on the cloth/resin layup then a 
solid plastic film, tape down firmly both layers, second larger than the first, 
and use a plastic applicator to push out any air bubbles, on the airliners we 
use vacumn( 21" hg) for air removal and pressure & heat for curing, probably 
wouldn't work on a KR. THE NEW " SARAN WRAP " with the cutter works 
wonderfully. layup is commonly done with the first piece the size/shape of the 
hole then up to four layers( depending on original thickness) each 1/2 larger 
than the first on all sides layed on in reverse order. the easy way to 
accomplish this is to first work epoxy into the cloth between two pieces of 
heavy plastic film,draw the shapes needed,cut out, and peel-n-stick. if you 
want you may call me at 816-305-9689

  Subject: KR> hole in LE


  I am going to have to patch a hole on the leading edge. matching the 
  contour is easy, but do I have to remove all of the paint, primer, and 
  filling down to the glass to get a good patch adhesion on the 1-2 in around 
  the hole.
