In today's new automobile painting technology that has less and less tolerance, deep scratches and over-sanding become a big concern, now, Introducing Insta Finish Foam discs. The open cell structure is used to keep the water in the Foam during the sanding operation. The water is not thrown out and a smaller amount of liquid can be used. The foam provides an even surface pressure to the abrasive fabric regardless of the form variations of the sanded material. This prevents the abrasive fabric from cutting through the lacquer layer, for example at sharp edges and corners. Why Foam Discs: Our Foam Discs are unique, multi-functional sanding material developed for tackling both smooth and profiled surfaces. Its flexible construction allows it to create a smooth sanding pattern on angled surfaces and edges while minimizing the risk of pressure marks. The flexible weave also allows water and air to pass freely, making it suitable for both dry and wet sanding, by machine or by hand.
