no, Claybar will remove little spots of tar, tree sap, road grime, basicly any crap that sticks to your paint work that doesnt come off with normal washing.

I was amazed at what came off my car when i clayed it, even after washing it. Once it was clayed and the paint nice and smooth and clean your ready for the polish to have a nice clean base to start on, i polished it to clean the colour, sealed it with ex-p sealer to lock the polish in, then waxed it to give it a water resistance glossy finish.

For swirl removal you need a proper polisher machine and polishing pads with a swirl removing compound. From what i understand Swirls are small scratches in the lacquer layer that reflect light at different angles. by using a polisher with a light cutting compound the lacquer can be buffed and repaired to remove the swirls so that light relfects off the paint underneath and not the lacquer layer
