I use this buffer daily. I use the Rupes pads and cutting creams. It does an awesome job removing scratches and scuffs on automotive paint. As other reviewers have said, if you’re doing full cars you should get a corded model. I have done full cars with this one and it takes 4/5 5ah batteries to complete the job. I have multiple Dewalt tools that require a fair amount of power and have found that you need at least a 5ah battery. If you try to use the smaller batteries, you will drain them almost immediately and will hate the tool. The bigger the battery, the longer it lasts (obviously) but the weight difference is shocking. If you’re doing spot work, I recommend a couple of 5ah batteries and you will be happy. I carry my equipment in a backpack and by the end of the day every extra pound feels compounded. Most of my work is spot repair. I do mobile paint chip and scratch repair. The cordless model allows me to work on vehicles without being near a power source. It has plenty of power when you put a lot of pressure on it and the overall balance is great. Over the last couple of months, I couldn’t be happier with this purchase.

This thing works Great! Lots of speed control adjustment. I have hours and hours of use on this thing, polishing my boats and trucks, and it keeps going strong. It does get heavy when using it a lot, but it is a trade off I was aware of when getting a cordless polisher.

Perfect for polishing automobiles. It's a bit heavy but it is very easy to use. Speed control works well. I used 4AH batteries with mine and it lasted nearly all day. Quality tool from DeWalt.

This is an amazing polisher! The caveat is that it is VERY heavy with a proper battery---so heavy that I only use it on the top panels of anything I work on. If you're a body builder, you might be able to fully cut a couple cars with it, but for me, it's strictly a hood/roof/trunk top polisher. Quality - This is in top-end territory for performance and overall quality, easily matching the top-end polishers from rupes et al. Plus, you're buying a tool from a company that actually knows how to make tools. Yea! I have no doubt it will last as long as you want it to. I've run over many of my Dewalt XT tools before with my truck and they keep on keeping on. Batteries - If you're looking at buying this and are not already invested in Dewalt batteries, plan on spending at least $160 on a couple of 6AH batteries. The 5AH batteries work, but will only run around 45 minutes each. The 6AH ones perform much better, you can expect over an hour out of those. Since I only use this on the top panels, 2 6AH are more than I need to finish a car. If you're planning on using it for the whole car, you're going to need more than 2 6AHs for a mow down, and even more if you're going 2-stage. Overall - This is going to be a game changer for most detailers. The weight actually helps on the top panels, I find it to be the perfect amount of pressure and can just steer it around. Not having to worry about the cord is worth it, along with the huge benefit of having something that doesn't require electricity for remote quick defect removal. It's an excellent tool, but I highly recommend that you have a lighter, plug in DA for the sides in addition to this. It's just too heavy to be your only DA IMO. If you're a pro detailer, just buy it already. It's a complete game changer.
