GL: Bottom paint advice

[John & Judy Gill]

I hate to disagree with Tommy, but barrier coats (two part epoxy) is  
a very good idea on brand new boats to prevent gel coat blistering.   
It is also a good idea to apply a barrier coat on a boat which has  
started to blister (after all blisters have been properly dug out and  
dried -  you do not have to remove the entire gel coat to apply a  
barrier coat.  The problem started when boat manufacturers switched  
from all acrylic gel coat systems to co-polymers of styrene and  
acrylic to save money.  Note that all bottom paint must be removed  
and the surface roughed up to provide goo adhesion of the epoxy  
barrier coat.
