If you look closely at the picture, you will see there are hundreds of small blisters the size of a dime/ nickel. The only way to truly fix the blistering at this point is to peel the gelcoat and let the hull dry. There are other ways of fixing the blisters but chances are this will be a re-occurring problem unless fixed right the first time. Regular hull bottom maintenance and application of barrier/bottom paint will help prevent this.
