ARrrrrgfhgghghh!!
So i just washed my car today and lo and behold, I have managed to induce swirl marks.
Perhaps I need to buy new sponges and towels or something. I managed to go over 16,000 miles without them and now--BAM all over the place.
Time for a visit to the detailer to have the swirls removed. Need to go re-read some of PerfectLap's threads too...
