If you're serious, check the price for the assembly for your car. Mine is $110 for the pair and replacement isn't that difficult. It seems wasteful but from some of the comments from previous threads the polish jobs don't hold up that well.
3M kit worked perfectly for me, I've used it 3 times, two different vehicles. Came out very clear, 95% improvement, lasted probably 5 years, for $15. They include the buffing wheel attachment for a drill.
Nobody discloses the composition of their headlight finishes and I know there are numerous patented substances. I would probably best trust one from a knowledgeable company like 3M.
Nor do many of the "third party" or "aftermarket" replacements. Many just plain do not fit properly (are difficult or impossible to properly aim, for instance) - many leak, and many do not stand up well to UV and/or Ozone. Also, many scratch easily - So, you pay your money and you take your chances.
I used a 3M kit on a 2002 Toyota a few years ago, with great success. I sold the car about a year after that so I don't know how long the fix would have lasted.

Thread redux of some couple months back on "Where, oh where did my glass lens covers go..." :)
The 5 year number is for them to get fairly cloudy again. If you want to keep them close to clear, maybe every 3 years. They also have a variety of products to put on every month or so to help keep them protected. I have one, but can't seem to remember to use it.
