I was recently doing a single stage detail on a one year old black Lexus which was somewhat neglected but not horrible. After a foam wash and once over with the Nanoskin mitt I went to work with the Flex 3401 and XMT 360. I was using a white 5" hybrid pad. I did a couple of body panels and pulled the vehicle out in the sun to check the results when I noticed holograming from the 3401. I have never encountered this problem before or at least did not notice it on lighter colored vehicles. I switched to the Porter Cable with a CCS pink pad which corrected it fine and I finished out the vehicle with that. I try to use good technique with the Flex 3401 along with clean pads. I fell in love with the 3401 at Mike's boot camp but I am now having second thoughts. I would have been horrified if that vehicle had hit the streets in that condition. Has anyone had any similar issues with the Flex 3401. Any suggestions?
