Another detailing tidbit I learned today:
If you use spray detailer on a car after you have rinsed it off (from being washed with soap) but before you dry it, it comes out awesome...I used Mothers Showtime detailer.
The detailer acts as a lubricant, and it also adds smoothness and a deep shine.
My detailer buddy told me about it and I didn't believe him. I'll do this more often now. It also made drying the car faster.
