OK, I've checked the archives, but not before buying Interlux Heavy Duty Stain Remover, which has proved to be absolutely worthless.I'm trying to get rid of the brown along the water line on my h23. The worst of it was on the transom below the motor mount. After getting nowhere with the Interlux, I wound up sanding it off. The rest, though, is on the painted bootstripe.Reading the archives, the best products to try next are Slimy Grimy, FSR and Sno-bowl. I'll start with Slimy Grimy, unless somebody has a better idea.I also saw on the Internet that bootstripe tape is available, which Don Casey says is an option, although it won't give an even perspective as the hull moves to different angles. I'm not real thrilled about painting, but I guess that's an option.Any ideas will be appreciated.Mac
