Yeah thats what I said in my first post, good for wax actually prefered because I wouldnt have to reverse direction around the car so the cord isnt wrapped around it. Thats pretty cool it has been done already though I definitly had no clue. I wonder if they didnt catch on because of poor operating characteristics or the market just didnt have a big need when these were being produced. I would definitly buy one to spin some 3in pads in wax and go to town!
It's probably a small market. Most detailing enthusiasts park the car in question in a garage; reaching for a corded tool is just as easy. I also think they tend to market these things wrong; calling them polishers. They lack the power, and the longevity. Many complained about not being able to do a correction on an entire car with one of these with one battery. But if they can do 3/4 of a car with paint correction; I ought to be able to machine apply wax/sealant to both cars and both motorcycles on a battery! I could also see it being useful for spot correction if it had the power.
