The CtD TruCut Conditioner is designed to extend the life of your sanding pafs. This conditioner creates a balance of lubricity that allows the pad to keep cutting and reduces friction created during the sanding process. By adding this to your sanding process, you will increase the life of each pad by up to 4 times compared to using the pad dry and produces a cleaner cut. This product also traps the dust and allows it to pass through the sanding pad and provides a consistent finish.
