I have uber, n914, liquid crystal, blackfire, mckees, the whole autogeek lineup. Car doesnt even stay clean for 6 hours with all the pollen out there right now. then you get water spots from the morning dew. Then its 90 when I get home and the sun is blazing on the car so I just can't win. It's a merciless hobby trying to keep the car looking clean this time of year.
