Unless you have a buffer theres no way to remove swirls completely. Some people use meguairs swirl x by hand and soften the edges of the swirls to make them less noticeable but its ALOT of work without a buffer. Best bet is to take it to a professional and have them correct the paint. Unless you want to invest some money in getting the right stuff and do it yourself
i can get pics later today, its dark out, although i used Fade to Black from glimmerglassdetailing.com on the engine bay and its GOLD!. lol looks amazing i need some crome polish for my mrz products
