Recently, I had a chance to see if paint cleaning clay really works. I've been restoring a 40 year old Colnago road bike and on a nice Fall day a month or so ago I painted it at my shop. I used Eastwood two-part epoxy (real catalyzed automotive paint in a spray can) and had a large fan venting the overspray out of the shop.
Well, I just happened to drive the FFR over to the shop that day and, although I thought it was upwind and far enough away from the door, it ended up being covered in a fine dusting of overspray. Even though my car is a deep green and the bike is a bright orange, you couldn't see it.... but you sure could feel it on the surface.
My first thought was to use an orbital and buff the paint, but a friend recommended I use paint cleaning clay. I had a chunk of it laying around (still new in the container from Griot's Garage) and used it with their recommendation of Speed Shine as a surface lubricant. I was amazed at what a great job it did and without any real effort - I'm now a convert to the wonders of clay. Not only did it do an awesome job cleaning the surface, it did so without removing any of the clear coat.
Here's a pic of a hunk of the clay after just a few light passes over the front fender......
The clay is yellow and the redish-orange is the paint and other impurities it removed.

Further to the above, you might not need the swirl remover (which is an abrasive hence best avoided if at all possible). Clay DOES strip off all contaminants and protective layers so you WILL want to reprotect them with wax/acrylic sealant but if the paint was only lightly contaminated before you clayed it, you may not have many swirls to remove. Try the wax/sealant first and only if you see hazing or artifacts should you hit it with anything abrasive.
I use a clay bar on my nicer rides. I have to lay a towel or tarp on the ground. If you drop the clay bar, it is over. They now have a clay towel, easier to hold onto. Clay works great and does not damage the paint.

The bike is gorgeous. I ride a 1976 Bianchi that I purchased new (I'm 66). I'm tempted to refinish it, but won't because I know I'll do a lousy job. I also ride a Raleigh Professional from the 1970's. My wife has a beautiful Gios Torino. In the winter I ride a more modern mountain bike to work. I also have a 1968 Triumph 650 Tiger. Way too many toys.
There is a beautiful ghost sign in Albany NY that I ride by everyday on my way to work. zoom in on the badge. Colnago fans may appreciate it.
Took years to convince me clay was a good idea (seemed so wrong). Used it on a truck I didn't have a lot of feelings for and became an advocate in the right situations...da Bat
Also a fan... Had the misfortune of thinking my other "toy" was far enough away when I was rattle-canning some parts. Nope... had about 24769470047690 little blue speckles all over "Blackie".
