Check out the video at that link, it'll show you the results.
I swear by this stuff. Used 1 application on my SVX AND my buddy's 99 grand cherokee (2 applications per package). His lamps were completely yellow, to the point that you could barely see the bulb. Afterwards, they looked like brand new lenses. That was in December. They still look just as good as the day I did them. Same results with the SVX lights.
For $12 and 5 minutes of work, how can you go wrong
I have an extra application here if someone wants to give it a try. $5 and shipping and its yours. Shoot me a PM
