The hatch on my H260 has scratches from being slid fwd and back. I think I eliminated the source of the scratches. But want to buff them out.Tried 600 sandpaper on a small portion. The more visible scratches disappeared but of course now I have a dulling of the surface. I've read that toothpaste and some other similar abrasives will bring the shine back.Any experience with this problem or did you just ignore it?
