*This must be done when headlamps are cool. recommend you do this in a cool, shaded area. Clean Headlamp lens with windex, using terry cloth or sponge to remove dirt, bugs guts and any road tar.
*Apply Mirror glaze cleaner first, using terry cloth in a circular motion. allow to dry.(1 min)Buff clean, re-apply as needed to get clean.
Apply mirror glaze polish after first initial cleaning. Buff using terry cloth. Re-apply again if needed. If the dull is on the outside of the headlamp, you should see big difference in clarity.(If it is on the inside of the lamp, it may need replacing)This also can be used on dullness or scratches in plastic tail lamps also.
