When I purchased Half Magic, it had huge chunks of antifouling paint peeling off with the bare gelcoat (in pristine condition) revealing underneath. My boatyard hired an outside contractor to soda blast and charged me $875 for the service. There was another $2500 in charges for 3 layers of barrier coat and antifouling with prep work and sanding in between each layer. The result was a nice smooth cruising bottom that has held up well for the past 3 seasons (with touch up to the antifouling each spring).
Our boatyard (and many in our area) doesn’t allow any owner sanding done to bottoms due to issues with clean up and environmental liabilities.

Opinions and experiences of the list are welcome before I proceed with it (or stay with the sanding method).
