Buffing...is it bad?

Buffing CAN cause swirl marks, but most of the time it's either intentional or because you're doing it wrong. Always make sure you have a clean buffing pad. NEVER use a pad after you drop it on the floor or let it come in contact with anything soiled with any sort of grit. Make sure you're using the right pad for the right application, and make sure you're using the correct compounds.

I totally agree. Also, using a clay bar after washing the car will remove allot of debris from the paint. By removing this additional dirt, and always using clean pads (as mentioned above) I get pretty good results with my Porter Cable. My detail procedure is as follows:
1) wash (with dawn)
2) clay bar
3) wash again (new water soap)
4) polish (somtimes I use a cleaner first)
5) glaze (optional, but good for balck)
6) wax

I have a hard time believing that someone would "intentionally" polish your car so it would have swirls after . No, it's because they have no f@#$ing idea what they are doing. Most if not all high volume shops really don't perform a quality detail. The reason isn't always because of lack of knowledge, it's because you can't charge a reasonable price and spend all day properly detailing a car. It's not profitable, you would go broke. If it's a small operation with little to no overhead, it's doable. You have to charge serious amounts of money to run a big business like that. Just something to keep in mind. You should never let someone detail your car until you have seen their work first hand. It's a very good idea to use someone that someone you know has used and is very happy with.
