[Alberg30] barrier bottom protection

[Mike Lehman]

Great discussion! With all of the varying opinions about barrier coating 
older boats like A30s, I have taken the approach to "sit back and watch". 
It's a big expense and a lot of work, and I am not prepared to invest in a 
barrier coat until I have more consistent reports. Of course, if I had a 
problem, I would do something to fix it, but short of that, I ain't touching 
it. I have postulated a theory though, and that is, I think it's possible 
that blisters may be created from the water inside the boat, not by the 
outside water. That is water which is trapped in the glass that can get out 
when a barrier coat is applied.

Well John, I make it four in favour, seven against, with Chris's
votes counting one for, one against and one 'I don't know". Ain't
democracy wonderful?
Still, every writer who has done a barrier coat has experienced problems...
