So, looking at this from a different angle....is there any reason to "not" sandblast all of that old - thick - layers and layers of paint off, get 2 coats of barrier epoxy and start with new paint? Having the biggest blisters ground out while they're visible.



I was working on a bottom job once and a steel boat was next to me being sand blasted. I wondered about sand blasting my bottom and asked the guy to hit it with his sand blaster. Sorry I did that. He only did about a few square inches. It not only took the bottom paint of but to the gell coat and beyond. Soda blasting could be an option or crushed walnut shells or some other soft abrasive could work. Just don't use sand.
