I have a black 2002 RS and I feel your pain. Try using the california water blade to dry the car off. I go Zymol the whole way. Wsshing the car in total shade helps ALOT. I wash the car in the shade then pull it in the garage and dry it off. Another tip to keep the swirl marks down is to stop using anything that touches the ground. Don't mix towels around either. Use a set of towels for drying, waxing, etc..
