ABSTRACT:
A composition and method are described for repairing surface defects in plastic objects, particularly laser-readable discs such as audio compact discs, video laser discs and CD-ROM discs. Using the composition and method, a surface defect in the disc is smoothed over and filled with a waxy material having a refractive index approximating that of the plastic substrate, thereby forming a repair which does not distract the laser and permits continued use of the disc.
