I did check them out Zach, in fact I read both your review and Brian Guy's review of the Rupes 75E. At the time I didn't realize you were the same guy here. You guys were both very helpful in my selection of polisher. From earlier research I was leaning towards the Flex 3401, but after reading your reviews I felt Rupes would be the best choice for me.
I bought the Rupes Duetto as I thought it would be the best compromise for my use. I will only be doing my wife's car and my cars, and maybe my motorcycle. In fact one of my questions to Reece was whether I could change the back plate so I could use 3" pads, but found out that is not possible.
I bought the medium coarse gel, the fine and the ultra fine along with their corresponding pads. I started on my wife's car (she thinks I put her first, but really I wanted to practice on her car in case I made newbie mistakes
). Really though her car is a 2001 model and better to learn on that car any way. I think I probably should have ordered the coarse gel since her car was more scratched and blemished than I thought. I had to go over several areas multiple times with the medium, and still it is not quite right. However, it does look significantly better than it did.
I haven't gone any further than this step because I re-aggravated an elbow injury and I have to take it easy for a while. Since I am not going to be able to get back to her car for a while, I think I may order it.
