Over the last few years I've mostly used the Levon + Jesco method with variable speed grinders and vertical soft wheels and the Cyclo dual head to finish. My spouse is interested in getting involved with maintaining the polish but the method I've used is messy and equipment too heavy. Have you found an easy to use lightweight machine you would recommend?
I've noticed, for example, the Griot's Garage 6" random orbital that is under 7 pounds and has two handed grip. Reviewers rate it 5 out of 5 but these are folks polishing cars.
If it were easy, the PO would have done it.
