There was some discussion about this way back, but I am not well set up
to search all the previous mail of the Europa group. It is a fact that
sailplanes are made by first spraying a coating of gel-coat into the
mould and then laying up the epoxy and glass on top of it. The shrinkage
is a problem that we have with the tailplane of our 20 year old Slingsby
Vega at the moment. Although it doesn't need a gel coat replacement, it
does need filling to restore the original profile.
