I have no swirls on my 08GT that I bought new! I NEVER wash it with nothing but my soft wash mit and rinse it down for extremely well before I scrub on it, so that I dont grind dirt into the paint scratching it. Hardest part is getting it dried from water spots in the summer. I find my self washing one panel at a time and wetting the entire car down to keep it wet. My car spent the first 2 years of its life outside and Ive only waxed it twice since May of 08! It is still swirl free. I bought my car to drive and race not sit around and take pics so I feel its a waste of time spending to much time waxing it. After one drive its dirty and a whole Sat of work is un-noticed! Id rather spend my Sat slinging tire rubber on the rocker panels! LOL
Ive had 5 Black cars and said Id never have another one everytime but I just cant say no.
