Query: This product won't work fro dark colored cars.

After reading many reviews of the microfiber three pack I decided to try them for my new 2011 black camaro. I don't know what the color cars the previous reviewers had but it wasn't black.This has to be one of the worst drying cloths I've ever used and I've used many in the last 20 years. The car was never completely free of streaks until I used a microfiber cloth from Wal-Mart and completely went over the car a second time.Again, it may look like it does the trick on other vehicles but it won't work on a dark colors.--------------------------------------------------------------------------------
