Auto body repair & detailing: swirl marks, car wash soap, swirl marks

Question
What would you reccomend for treating swirl marks on a car? Is there something that I can purchase or send my car into the shop for that will eliminate them, not just mask them? If so, how much would that range from? If not, then what is the best most economical way for me to treat the swirl marks?
Thanks

Answer
You need to have the car buffed and polished.This could range from $150 to $400 depending on the condition of the paint and size of the car.To eliminate this problem in the future use a good carnuba type wax and avoid brush car washes.Hand washing is best and if you are unable to do it yourself it is worth the extra money to have some one do it for you.Also if you do it yourself use car wash soap not dish soap this is also bad for auto finishes.
