Rain Drops Detailing Supply 21mm v1 DA polisher is a sure bet to save you time and increase the quality of your work. Super comfortable and field tested for months on a wide range of projects from AIO (All In One) application on single stage vehicles, to multiple stage corrections without issue. Smooth and surprisingly powerful for the price point. This makes a great polisher for almost any shop, and an economical backup for high end shops with more expensive machines.

    Great option for 21 mm long throw

    I've been needing to up my polishing game and this was one of 3 I was looking into. The maxshine and Griot's we're the other 2 I was looking into. But between mixed reviews and a hefty price tag this hits all the marks. Affordable, quality made, smooth, powerful and also supporting a local business, I'm so glad I purchased this. Cuts my compound stage in HALF and doesn't stall even when I applied a lot of pressure. You won't regret this purchase.

    I was in a bind when I was in the middle of a detail job because my polisher had gone down. I needed something quick and in a hurry. Well I reached out to Ryan and he was a life saver. I ran to his shop and picked up one of these polishers. I got the 5 inch backing plate with and I was able to knock the job out in the time for the customer to pick up. This machine is smooth and easy to control. It doesn't tire you out over a long period of use and has great power. Whether you are just starting out or a pro, this is an around great machine.

    I used this for 6-7 hours straight and it worked flawlessly! You can’t beat the performance for this price. I used the 5” backing plate with this DA and that worked great too. I would definitely recommend this to anyone looking for DA!
