[Rhodes22-list] Re: HELP!! CB trunk has delaminated!

[Lou Rosenberg]

   Roger,
  I soon realized that I would never want to use a Sawsall on the 
trunk!  A drill to pierce the thin layer of  FRP that has bulged 
outward and then a few taps w a strong wood chisel would do ..  The 
manufacturer didnt lay up any glass mat there .
