[PSUBS-MAILIST] material question

[Alan via Personal_Submersibles]

Hi Emile,
my brother-in-laws fibreglass yacht has been sitting in the harbour
for at least 30 years, so pretty impervious to water.
The glass in the fibre would not crush, but the resin around it would squash
a little under that pressure. I would think the resin would seal any exposed 
fibres by squashing around them when put under that kind of pressure.
What are you sending down that deep?
