I'm so glad 2 Sand sent out an advertisement for the cleaning stick. I never thought of that. I do headlight restoration work and use a lot of the 3-in sandpaper. after a pair of headlights I would typically toss the sandpaper as it was beginning to fill with the polycarbonate and plastic. Not anymore The stick works wonderfully a couple seconds on the stick with my orbital sander and the sandpaper absolutely looks new and it acts that way too It cuts like new. Thank you so much for recommending this product.
