REFLECTOR: hanger rash

[Douglas Holub]

I'm no expert, but if it were mine I would just sand down to good glass, fill will pour foam, sand the shape, paint the foam with slurry, and then add a few layers of BID, staggering the edges so that it's easier to finish smooth. You've got to admit that 3 layers of cured BID is a heck of a lot stronger than doped fabric.

  Ok it's in the garage so it's not "hanger rash", and it's deep enough that it prob doesn't qualify anyway...
  My wing fell as I was building / placing it on a shelf.  The outboard side of the vertical stabilizer hit another shelf, just hard enough for the coner to poke a hole in  the glass.
  The hole is about 1 1/2 by 2 inches,  it's just aft of the leading edge. (I hope the pic comes through)
  I have never tried to repair anything like this...

  I assume (that's the part that worries me)  that I need to sand the filler off.
  remove any other damaged glass.
  fill with pourfoam, and glass over the spot.
  Originally it was made of 2 layer of uni offset in direction by a few degrees. (leading edge / trailing edge)
  So I was planing on going back with 2 layers of uni, offset the same way
  Overlapping on to the good glass.
  I was thinking of the 1st layer going about 2 inches on to the good glass,
  then the 2nd layer going about 1/2 inch farther than that.
  That makes the patch about 7 inches across.

  Is that way overboard, OK, or not enough???
