I just bought a cheap random orbital polisher and used meguiars polish, finished with turtle wax. Also did a clay bar the weekend before. It did not get 100% of the swirl marks out but it made a big difference. You'd need one of the nicer orbitals to get all the imperfections out but that wasn't my top priority.
Fit four wheels and tires for my wife’s Jeep Grand Cherokee in it. 20’s with 265/50/20. Two in the trunk/hatch, one on the back seat, and one on the passenger seat. That is with having a full Recaro baby seat and a booster seat. I definitely missed a photo op but was amazed it all fit. Now to surprise the wife.
