Mutch less expencive than Pettit with better reviews. With the slowdown it gulf drilling, the work boats are idle and divers attest to clean bottoms. I'll post an update when I see results.

I just ran accross this thread now. How did it go?

I think you made the right decision. I'll disagree with most other posters. I think soda blasting is the way to go. I was going to do my own bottom job. I started with the chemical strippers, which did pretty much nothing but make a big gooey mess. I decided to turn the job over to the pros, who have the experience and equipment to do it and do it well.

That in itself was a project. I called many yards throughout New England. Many promised quotes. Only one delivered. I want to the Newport (Rhode Island) boat show. Twelve yards promised me quotes "within a week." Guess how many provided quotes? If you said zero, you get the prize. This at the height of the recession. I finally gave the job to Lars Guck, of Guck Inc. in Bristol, RI. His references were great and he encouraged me to come by frequently to see each step of the work.

It started with the soda blasting. All the paint was gone, and every blister was opened up. Every blister was then sanded to remove the rough edges and filled with epoxy. Then sanding. Then the barrier coat. Then more sanding still. More barrier coat, more sanding, wash, rinse, repeat. Then a hard paint, Baltoplate. Then sanding again. More paint, more sanding, more paint and finally, you guessed it, more sanding.

Here are some pictures at various stages:

During the job, they notied that all kinds of crap had been attached to my keel along the years. Fiberglass. Wood. Eben foam board and bondo. They brought it right down to lead, had a computer design a template for proper shape, and fixed it right.

Yes, it was very expensive. The boat won;t be sold for many years now! At $55.00 per hour, if they do good work, you are doing very well.
