I used 5 star shine products I like it, I drive a 2000 lincoln, applied 5 star shine a year ago it still shines but it will lose its slickness but after reading all the complaints about a towel wont slide off, or it doent feel slippery anymore have you heard about pps cleaner it will restore the slide to your car surface and you can buff it! I use the cleaner every 3 mo. the lincoln shines on
p.s my sons cougar also shines on!
