I use Liquid Glass. It is a "polish" that works well on the swirl marks. It also helps protect your finish beautifully. It melts into the paint as it bakes in the sun to help protect the paint. It is also very easy to put on and take off with a rag. It's good stuff however at $23.00 a can its a bit more expensive than the pledge. It doesn't smell lemony fresh either. I might try using both? The pledge is something I wouldn't have thought of using before reading this post, but if Glider says it's good than I'll give it a try. Always learning good stuff on this site.
