LAST Record Preservative has been universally applauded by the super-critical reviewers and editors of audio publications. New records treated with LAST Record Preservative and kept clean can be played 100s of times without discernible wear--allowing them to be in pristine condition for future generations. LAST Record Preservative chemically enhances the molecular stability and therefore the cohesiveness of the groove surface so that it completely resists the damaging effects of stylus shock waves. The 30-second treatment affects the vinyl to a depth of about ten molecular layers and becomes part of the grove wall. There are no surface residues that can be picked up by the stylus. In fact overuse is harmless.
