Be sure to get the hull really, REALLY dry. I've heard tales of people 
who did not have blister problems until AFTER they put on a barrier 
coat. My theory is that Whitby's gelcoat was porous enough to let the 
hydrolization byproducts pass through without building up enough 
pressure to cause delamination, and the barrier coat blocked them.
