My 7 year old decided to spray suntan lotion on the sides and headlamps of my car and it was dried on before I discovered it. Needless to say I googled and decided to try a toothbrush with DAWN dish washing detergent. This worked pretty well on the paintwork but not the headlights. I'm looking at trying he below product for the headlights. MeguiarsDirect.com:Heavy Duty Headlight Restoration Kit Heavy Duty Headlight Restoration Kit Has anyone got experience with this product?
