A multi-component kit and method is provided to pretreat, resurface, and restore a plastic material, and in particular, the plastic lens covers over the headlights and taillights of an automobile. The multi-component kit includes a pretreatment formulation, a resurfacing formulation, and a restoration formulation. Each formulation is structured for application to the plastic lens covers by hand, thereby eliminating the need for specialized equipment or training. The method includes application of each formulation to the plastic lens covers using clean, lint free applicators. The pretreatment formulation is applied to clean the plastic lens covers and to prepare them for application of the resurfacing formulation, which repairs scratches and removes discoloration. The restoration formulation is applied to restore a high gloss shine to the plastic lens covers as well as to protect the plastic lens covers from the elements such as dust, dirt, and/or ultra-violet radiation.
