I tried it on my 2002 Lexus gs 300 and the results were not very good. I followed the exact directions that came with it. They improved but only for a few weeks-then they were cloudy again. Finally, i paid Lexus dealer $200.00 to do it with a product called BG. The result was very good, and 3 months out it continues to look very good. I do not reccomend Plastx, unless your headlights are mildly fogged. The BG is far better.
