I've got a Catalina 27 with several years worth of bottom paint on her. I plan to strip her down to the gelcoat and do a complete bottom job. I've read mixed reviews of various chemical peelers. I'm wondering if there's a consensus on one product that seems to work the best. If so, what is it? If not, and good ole fashioned scraping is the way to go, what's the proper procedure?

Thanks in advance for the advice!
