PC and menzerna didnt work? I just bought a new 350z and it had some pretty bad swirls, so I got to polishing. Well after hours of polishing with my orange pad and pc.. I didnt even touch the swirls, so then I got out my rotary and started with orange pad and menzerna with that on about 1000 rpms.. Looked good that day but after a couple of rains. Swirls are still there.. NOt as much but they are still there.. is there another really good polish I can use with my porter cable that will cut?
