The kit came with a towelette that you wipe the lenses as a final step. It says it takes 24 hours for it to cure so hopefully just waxing them when I wax the car will be sufficient maintenance. Although if you look at the damage on the headlight pre polishing it looks like road debris is a large contributing factor to the condition of the lense. Sunlight will make them hazy but the debris is basically sandblasting them.
