... Our boat is stored inside a building this year. The knucklehead who was next to me last year, not only painted his bottom (ablative) this spring inside the building without putting any protection under, but then went and wet-sanded the darn stuff. Pretty stupid. It's an untreated, unpainted concrete floor. What's the best solvent / method to do to remove the paint ? Scrub with Mineral Spirits ? It's been dry for a few months now. If you step in the area, you will wind up with bottom paint all over your shoes. Thanks, cheers, John
