I'll bring out my pom poms and join the cheer squad.
Mine was not a 10 min job because I had to deal with getting rid of those damned brown iron spots that plague white cars.
This product worked a treat. Spray on, watch the brown spots turn purple as they dissolve, wipe clean, rinse:
The only PITA is you wash your car before use, then wash it again after.
The Ultimate Fast Finish was a cake walk from that point, though. I will say it is a bit hard to use on a white car only because the hazing is so faint, you can't really see where you've applied the product. Really excellent results, though. If it works even half as well as I hope, given the minimal investment in cost and effort, I will be well pleased.
