Anyone still remember the Ultimate Detailing Machine David Bynon introduced almost 20 years ago? Still got mine, lol. That was the first polisher I have ever owned. The paint on my 2000 Eclipse was pretty hard so I bought a used Makita rotary off eBay shortly thereafter and kept the UDM for softer paint. I eventually found a used Flex 3401 on eBay for a stupid low price and bought it. So now the Flex is used for larger pads and the UDM now has a 3 inch plate for smaller pads. If the UDM ever dies I will probably replace it with a Rupes Bigfoot HLR75 cordless for small pads and if the Flex ever dies, I will probably get one of the Milwaukee cordless long throw DA polishers.
