Hey Guys. I'm looking to do some hull cleaning starting in March up until about this time next year. As far as i can tell I'm going to need a scraper, some sort of bristled brush, and a suction device is there anything else i'll need, aside from the SCUBA equipment which I already have. I also have a question about using an air-powered grinder, with some sort of cloth or padded wheel to make my work easier? Could that be done? Would it be worth it? Thanks
