You can trust that this item works well and does not scratch your paint. I was always skeptical previously and just asssumed these things scratched the car. But my paintless dent removal guy uses one and highly recommended the California Duster to me. He is fanatical about keeping his car totally detailed. And this product works so well that he never even washes his car unless it gets rained on. He just dusts it every morning before he backs out of his garage, and if needed he uses some liquid instant detailer and a microfiber cloth after dusting if he feels like it. It takes a total of less than 2 minutes to dust off an entire car, yet the result makes your car look like you just washed it.
