If you have any problems on Wednesday feel free to text or call me. I'm in manhattan. I also had problems with the 105 and my GG polisher. I was used to a dewalt rotary, or the Flex 3401. I found that if I slowed the speed down to about 4.5 or 5 and used a little less polish I had better luck with the dusting. The heat and humidity in Kansas in the summer plays hell on us at our shop when we buff/polish.
