[C320-list] bottom paint

[argates2nd at comcast.net]

If the sandblasting is intended to remove all coatings down to the gel coating, as would certainly be the case if any blisters are detected, I think you need barrier coats rather than just a primer. 
I used 4 coats of Petit Protect 2 years ago followed by 2/3 coats of Trinidad SR for FL saltwater.

Subject: [C320-list] bottom paint 

I'm about to have the first bottom job done on my 12 year old, freshwater 
boat. Without much in the way of available options on who will do the work 
and how it will be done, I really just need to decide whether the estimate 
that I've received is reasonable. The yard will haul it out, sand blast the 
bottom, then pressure wash the bottom and hull sides, prime the bottom with 
a light coat of bottom paint, then go back with two heavy coats of 
anti-fouling bottom paint, and then apply a third coat along the water line. 
They use Petit Un-epoxy Plus bottom paint. Any blisters would be dealt with 
separately. 

Is there anything about this approach that seems wrong? 

Thanks,
