OK, I am about to attempt a bottom job on my Catalinia 22. (First one for me ever, and in 7 years for the boat) I expect to have to fix some blisters, and maybe repaint with a barrier coat.
I was hoping to save some time by using a sand blaster to clean most of the old paint off to bottom, and to open up some of the blisters. Is this a foolish thing for a non-pro to try? I really am worried about the extra time, effort, and $$$ (yard time), that have to scrape and sand the whole bottom by hand.
Thoughts? Better ideas?
