High pressure and hot water are bad news for paint. especially new paint. If you are going to wash it you need to use something very soft like a cotton wash cloth that is very very clean. Nothing abrasive. And there basically is not getting rid of the swirlies. Thats from using the palm sanders to sand down to the metal. Its in the metal not just the paint. Buffing might help some but wait until the paint is cured just in case.. The compound and conditioner used for buffing is usually very abrasive and is also used for removing railroad dust, dirt, etc from the paint. Also check for any overspray in the paint. It will feel really rough. Its hard to see so just run your hand over it after washing it. If that happens get a clay bar kit. The'yre like 10 bucks. It'll have instructions on what to do. That will remove any overspray and dust, dirt and all that crap from the paint. Sometimes detail shops forget to check for that. As for drying techniques, no matter what the paint's age, just drive down the road for a while. The wind will take care of most of it. Whatever it doesnt take care of, use a terry cloth. By the way, nice car. Beautiful color. Peace.
