Hi Ron,
Providing you have a reasonably quiet workplace (and a reasonably
good hearing too), tapping the area in question with a coin. you
should quickly hear the difference in sound...it=C2=B4s like ultrasound
inspection without the ultra:-)
In spite of having been inactive on the building front for far too
long, I want to thank you for your ceaseless publishing of
your trials and errors!

I just finished doing battle with my instrument module taking out
about 1/2" warp of the 3/4" warp that tapered from middle to the
right side (right side being the worst).
I was careful heating till it became slightly soft then clamped
module flat. After leaving over night clamped flat I floxed on
plywood and 2 BID over plywood then clamped that flat overnight. Nice
fit to firewall now and flat/ stiff.
However a whole bunch of blisters occurred on the gray gel-coat
ranging from 1/8" to 1/16" in diameter after I heated it. Upon
cutting out blisters observation is everyone of the blisters has a
void under it exposing shiny polyester resin, some of the voids quite
deep and the gelcoat quite thin. I am afraid especial on cowl (perhaps
doors too) after final paint once heated, blistering may occur.
Any ideas best way to identify any voids on gray gelcoated parts?
I picked up my kit 04-2003 Kit # A265.
Thx.
Ron Parigoris
