Review on Sonax (288200-755) High Speed Wax - Ultimate Protection for Your Vehicle - 16.9 fl. oz., Red by Mike Flyers

If you have a black car, look elsewhere. This wax leaves streaks and has an oil film that cannot be wiped off. It might not be visible on light colors, but it was terrible on black. I ended up polishing the car with my old favorite Nu finish. It's been around forever and you can buy it for less than $10. Of course it's a rub, let dry and wax buff, but honestly I found it less labor intensive than trying to remove the film of oil and streaks left by the Sonax Speedwax product. I followed the directions and only sprayed the door a couple of times, but the film quickly worsened my condition.
