Great update! What kind of moisture meter was used when you did the measurements? Can you provide any moisture mapping info (readings/position)? Having launched last month after completely stripping the bottom to gelcoat (couldn't see any blisters), new barrier coat and VC Offshore, I'm not real keen on wanting to look for problems, but on a boat 25 years old I know better. This would be a project that would start with measurements in the fall after hauling for the season.
