I actually just tried to get rid of my swirls today! I bought a DA polisher, some pads and some Meguiar's swirl remover. I tried for quite a while to remove the swirls (after washing, clay bar-ing, etc) before giving up and returning everything to the store. Either the stuff definitely doesn't work as advertised on YouTube, the polisher was crap ($150), or I just suck.
It still looks good but it's not as perfect as I want it. Maybe I can find someone locally who can take them out for me.
