I'm probably gonna get slammed for this but here goes. SIP is an awesome polish. I have 3.02 that I had shipped from overseas. However, it does work best via rotory and high speeds. Even with the rotory and using very little polish it still takes some time to fully break down. I can't imaging using it with an orbital. In fact, if I stop using my rotory before the polish is
fully broken down it holograms like crazy. That's where the 106 would come in to clean up those holograms. Some polishes work best via rotory and SIP is definately one of them. If it's correction your looking for I wouldn't get too excited about your new free P/C. If you don't want to go the rotory route, then I would give some serious thought towards the
Flex.
