If the entire front lens is going to be replaced, by using the cutting method would be the far easiest method correct? To me its easier replacing the lens then it is to do a "headlight restoration" by sanding. if you cut around the entire lens and only leave where it attaches to the housing, it would make it much easier getting all of the rest of the lens off correct? Or is my thinking incorrect?

What lens would you use? I see stuff on ebay, but that isnt always the best approach.

Thanks
