I want to say that this is the best forum I've visited in regards to detailing cars. I registered instantly. I just bought a used car which has horrible swirl marks (the car is black, so it's easy to see). I was looking up ways to get rid of the swirls and found this place. I also found out that I've been washing my cars wrong. This is great for the information, but not so great on the wallet as I now have a huge shopping list for products. Keep up the great work and teachings.
