OK so is there a big difference in viscosity?

Cheers


Nah. bugger all...but there is a diference.


So you'll accept it's all in the osmotic pressure?

Cheers


All?
Nope.

So if there were no osmotic pressures there would still be blistering
below the waterline???

Cheers


I believe so.


Beleif is wonderful but how so -enquiring minds want to know!

Cheers


Actually Nav, without the osmotic pressure there would probably NOT be
blistering below the waterline.
Water would still penetrate the gelcoat, react with the chemicals in
the resins and provide the circumstances for osmosis, but if the
pressure didn't exist then thers wouldn't be enough force built up to
produce the blister.


Yes, I'd say that's right 'cos I've rarely seen blisters above the water
line...
