Hank,
When I purchased RumRunner, she didn't have a barrier coat or any  
anti-fouling, just bare gel coat. She also had a million tiny (smaller than a  dime) 
blisters.
I had the hull sand blasted, two barrier coats and two anti-fouling. From  my 
experience, I would recommend the barrier coat, simply as a cautious measure. 
 A little time and money spent now could prevent a larger and more expensive  
project down the road. You already have a great deal of time and energy 
invested  in this bottom job, don't try to take the quick route, finish it the 
right  way.
 
Rummy
