ScottWax may be the best person to address this being he is a cyclist also. My question being, will a bike rack mar my paint? If you ask any bike shop in town, they will say no but while I trust their knowledge of bikes, I don't know if I trust their knowledge of car paint. If drying a car with a bath towel will mar the paint, I can't see the padding on bike racks being enough cushion to protect the paint.
