I purchased a bottle of Lucas Slick Mist detailing spray at a car show I attended recently.  After a couple of hours at the show, I thought I would go ahead and try the Slick Mist on my 1985 Porsche 911.  The results were incredible!  My car only has 45,000 miles and still has the original black paint it came from the factory with.  After using the Slick Mist, people at the show could not believe the paint was 23 years old.  It looked like new!  I have not found any polish/wax that works like Slick Mist and that is so easy to use!
