ABSTRACT OF THE DISCLOSURE An article of manufacture and a method are dis- closed herein for improving lubricity and wear resistance of a given substrate by applying thereto a composition consisting essentially of low-molecular weight tetra- fluoroethylene telomers, an antistatic agent, preferably in the form of a tertiary amine, and a volatile organic solvent, and removing the volatile solvent to produce a thin, dry coating upon said substrate. The compositions herein disclosed have been found to be most effective as preservatives or coating gramophone or phonograph re- cords which provide marked reduction of record groove wear while substantially minimizing noise and harmonic distortion.
