Stylast, as well as the LP Preservative and other products from The Last Factory, is hardly junk, but rather well-engineered products by a chemist and LP archivist. Last products are used by The National Archives in Washington, D.C., hardly fools. The LP Preservative is not a coating, it is a PVC-bonding agent that is applied in liquid form. The liquid carrier evaporates, by which time the active ingredient has bonded the PVC molecules of the vinyl LP together, making it’s grooves far less susceptible to wear.
