Completely Prevent Record Wear 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. 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. Greg Weaver August 1999 Soundstage Magazine: "As to the preservation capabilities of the Record Preservative I can only speculate as I have no microscopes to examine the grooves of my records. But sonically it seems to offer much the same type of improvement as the Stylus Treatment but more of it. Midrange voices seem more pure and have more body; they are more truthful to the original voice and offer greater detail. Focus is a good bit sharper and with more detail uncovered especially near the noise floor. Again the microdynamic nature of the music is improved as are the separation and delineation of objects throughout the soundstage. Surface noise is again greatly reduced much more so here than with the Stylus Treatment alone. This stuff is smooth! The winning combination here is the use of a record treated with the Preservative tracked by a stylus treated with the Treatment. The combined enhancement of the two products on the sonic performance is quite desirable. And given that they are both purported to extend the life of both stylus and record what's not to like?"
