A) It is of course easier to repair, so let's begin with it first:
Grind off the afflicted area with 40 - 60 grit sandpaper, until the paint is
removed from the outer skin and the structure of the glass cloth is visible
about
6 mm (1/4 in.) around the rim of the hole.

FIG. 40
Fill the hole in the foam with epoxy putty which is made from normal epoxy
mixed with microballoons '
FIG. 41
Grind off the excess resin flush with the sound foam.
Remove part of the outer skin so that the glass is exposed for about 25 mm
around the rim. The exposed glass should be ground tapered so that it goes s
from zero to full thickness (ratio 1:40). Note that it will be easy to unwittingly
carve deep holes in the foam while attacking harder stuff. Do not touch area
with (greasy) fingers! Remove dust with clean brush.
