I should have flat out asked this before. I have used one of the headlight cleaning kits, 'Blue Coral Headlight Film Removal' kit. Well it has removed like 70% of the film, but it comes back fast, and now it doesnt remove more, it is making the car look like so old! If the headlights didnt cost so much, I would replace them, and you cant just replace the case. After replacing that starter, I cant replace the lights for a long time! So...has anyone else used something else that has worked better for you? This stuff worked ok the first time, but now it does not work. They are both getting cloudy, and it wont come off. So...whats everyone else using? That works.
