A boat in our boatyard had their hull soda blasted and it looked like concrete when done. They ended up having to do 3-4 coats of epoxy filler and then fairing the entire hull. I was envious when their boat was stripped in 1 day but then seeing the extra work and sanding required, felt great with my option to sand.
I redid my hull this year as well. There were many layers of ablative paint. I took down to gel coat / barrier with a 80 / 100 grit sanding using a festool sander. Already had from work which was a plus but would have bought it for this job alone. Then two coats of petit epoxy barrier and 2 coats of petit vivid over top of that. I must say, I love the vivid paint. Boats been back in the water 4 months now, on the river, and have zero growth. When scraping with my fingernails, nothing comes off, growth or paint, and the hull feels nicely polished. Overall it took about 50 hours start to finish at a casual pace working solo on the boat. If I didn’t truly enjoy it, probably not a money savings in taking time from work but satisfaction wise, would do again. As a side, last year I did the "1000 dollar" option, scraped off loose stuff, overcoat with 2 coats of ablative and it all sheeted off during the year. I have ideas of what happened, but I kind of knew i was putting a band aid on something more serious. Wasted my time and money. I’ve quickly learned with sailing there are no shortcuts.
