Well, swirl marks are very fine scrathces in the paint. So you will need something abrasive to remove them. Working by hand, this would mean using ScratchX. Be sure to read the How-To Section of the forum for removing scratches and using ScratchX.
DC#2 is a pure polish, that is it has no abrasives. DC#1 is a chemical cleaner, so it has no abrasives either.
If you use 2 polishes, your car wont explode... but there is no real point to it either. Some people will use a pure polish after using a cleaner/polish, but using 2 pure polishes together wont do much.
