I've got some slight damage to the boot-top from sanding the old bottom paint too close. It does not require a complete re-paint, only some touch up. The boot-top is the original on this 1983 boat, but it still shines where I didn't hit it with the sander. Marine supply stores are few and far between here, so I'm also concerned about getting something that can be used at the water line. Can anyone tell me what products might work for this job?
