Just a word of advice... anytime you have a boat media blasted... as in soda blasting, sandblasting or even wet abrasive blasted you really have to use some type of epoxy barrier coat on the gel-coat to seal it before applying your ablative paint.
I've seen way to many boats that were dry sandblasted and then the customer decide to apply ONLY ablative paint over the freshly blasted gel-coat.
The problem is gel-coat absorbs moisture as much as no one wants to admit... freshly sandblasted gel-coat has a tendency to get little micro pinholes which most of the time you can't see unless you look real hard.
Half the boats we wet abrasive blast... we also do the bottom painting and on those boats we either put 4 coats of Interlux 2000E of 2 coats of SeaHawk Tuff-Stuff epoxy barrier coat.
More of our customers are moving to SeaHawk Tuff-Stuff because 2 coats of SeaHawk Tuff-Stuff equals 4 coats of Interlux 2000E which saves a lot of time and money
Here's a video we shot this week of a badly blistered boat that was sandblasted maybe 10 years ago and then had only ablative paint put over the gel-coat without a barrier coat.
Badly Blistered Gel-coat caused by Sandblasting and no barrier coat

Had the boat owner done it right and barrier coated the boat there would have never been any blisters
This is what a healthy gel-coat should look like during wet abrasive blasting
