Well, you got two issues. 1. How to get rid of the swirls, and 2. How to wash and minimize swirls/scratches.
I use a two mitt and two bucket system. One bucket to rinse the mitts, and one with the wash soap. I have two mitts, one with those large microfiber worms and one with more of a microfiber fabric. I use the worm mitt first, and then the microfiber (one in each hand). Rinse in the rinse bucket, and then back in the soap.
Dry the car with a leaf blower (gas or electric). Don't use a towel except to pick up the dribbles after the leaf blower.
Now to get rid of the swirls. You'll need a random orbital buffer, some pads, and some elbow grease.
Sample Bill of Materials
Porter Cable random orbital polisher (or equivalent).
Dual-Action Hook & Loop Flexible Backing Plate 5"
White Lake Country 5 1/2 Inch Flat Foam Pad
Orange Lake Country 5 1/2 Inch Flat Foam Pad
Meguiar's Ultimate Compound
Meguiar's M205 Mirror Glaze Ultra Finishing Polish
Menzerna Power Lock
First clay bar the entire car with detail mist as a lubricant.
Then use the ultimate compound
Then hit with the finish compund
Then seal with Menzerna Power Lock.
After you clay, tape off your car before hand to prevent any products touching plastic. Blue painters tape is probably OK. There's also a technique to using the random orbital polisher you should research before use. I got most of my info from videos on Autogeekonline. The Meguiars ultimate compound is a nice, user-friendly compound (it breaks down into finer grit as you work it). And even though your car is fairly new, you should at least check the surface with your hand inside a plastic sandwich baggie to feel for contaminants before skipping this step. If you feel them, then use the clay bar.
When you're all done, sit back and admire your handywork
I'm not a professional detailer, or an expert by any means. Just a long-term owner of a black jeep. Swirls are inevitable, but if you keep up on it, wash with a swirl-minimizing method.... they can be tolerable.
Hope this helps and gives some ideas!!!
