I truly wasn't expecting much with these fabrics, however was I shocked when these scratches actually vanished in seconds with a touch of rubbing from this material. It arrived in a pack of two materials in individual sacks and a couple of expendable gloves. I wiped the territory with a spotless towel first to get any residue and soil off. With a bit of rubbing, the scratches that have been there for quite a long time simply blurred away. I am inspired. The materials are reusable as well. I'll chase for more scratches in the first part of the day. It was difficult to catch the scratches in a photograph, as the impression of my neighbor's home would appear rather, yet ideally you can see that the scratches are no more. I think about whether they would chip away at my old shades!
