Cheers for the comments guys, i'm glad to have finally got a car done to show you guys what i'm about,
The headlights can be caused by a few things, just general daily wear, stonechips, and UV sunlight, they can be treated using polish in the same way that paint can be,
In certain cases when the headlight is really bad you can use some wet and dry sand paper to great effects, and then refine with polish, but it is alot of work and elbow grease to do that, and ultimatly alot of $$. But can be done!
Thanks for the feedback
