From what everyone has ever told me the true only effective way to remove swirl marks completely is with a rotary buffer. I want to try a different machine than the crap ive been using so Im looking at a makita, and im also looking at a porter cable. But in reading these threads, autopia, etc. I get the idea the PC is just a really glorified orbital. (waits to be flamed) I mean, can you really get the same effect with the PC as with a kick ass rotary, or is the PC just a much safer almost as good alternative? Id appreciate any info you throw at me. thanks.
