Carl - I fit in the catagory with most of the testimonial people. I've only used it 3 times in the past 2 years. This is not because the product lasts this long (though it is the longest lasting polish I've ever used), it's because I'm lazy . . .
Swirl marks have never been a problem on my Blue '96 model . . . but for what it's worth . . . here is a QUOTE from the Finish First web site -
"Finish First meets today's tough standard of automobile paint/finish care by using advanced technology based on synthetic polymers, similar to the synthetic paint on your vehicle. This high-tech formula contains no wax, silicone or Teflon. Finish First uses a synthetic emulsion cleaning agent to dissolve old wax, tar, road film, dirt and organic contaminants which cling to the paint even after washing. With this dissolving cleaning action, you will not create those "swirl" marks into your paint finish usually caused by organic wax cleaners. Not only will Finish First not cause swirl marks, the cleaning emulsion will dissolve the contaminants in old swirl marks caused by previous waxes and make them disappear."
