Charlie, great posts above. I have yet to try the clay bar process, but when I get a spare moment around the house I am planning on using one on the '69. I used the chamois on my '08 but sprayed the detailer on the truck before I wiped it down with the chamois. After the chamois removed the majority of the water/detailer I came back with an extra soft cloth I had to finish wiping the body down to a clean luster.
One thing I did notice when using a chamois and detailer together was that I didn't end up with "water streaks" once I wiped off a panel. It seemed to use the water to help spread the detailer while pulling more water off the truck as well. Does that make sense?
Above you mentioned that you purcahsed high quality towels, are you referring to a microfiber towel? Mothers, Meguiar's...?
