My Review of the Flex XC90 VRG (Long)

Let me preface this review by saying my comparisons will be made to the PC and my limited use of the rotary (Hitachi). Also I will be the first to admit that if you have mastered the rotary you can do everything with one tool and this may not be a need for you, however if you are like myself and didn’t have the time to dedicate to practicing and honing your skill with the rotary this could very well be the perfect tool for you. OK so on to the review:

Out of the box: I must say it has the look and feel of a rotary. It could pass for the rotary’s little brother. It has the color scheme of the Milwaukee tool line with red, gray, and black. When I pulled it out of the box I immediately noticed that it was a solid feeling tool. It doesn’t weigh much more than the PC but the weight is very well distributed, thus making it feel very balanced. One of the first things you notice is that the backing plate is not flexible, but I had no issues with that at all. In fact, the lower profile it has was actually beneficial for getting under and around side mirrors. The backing plate is large and only 6.5” pads or larger will work but I am receiving a free smaller backing plate about 5” and will be able to use 5.5” and 6.5” pads with it.





The front handle reminds me of the Metabo, maybe it’s a German thing. I really didn’t think I would like the handle placement as I did like the bail handle on my Hitachi which was on top. However, I was pleasantly surprised at the comfort the handle gave me, plus as you will read later you need both hands on this machine. I also think the handle placement made me feel less vibration as compared to the PC because I usually palm the top of the PC when I use it.





The cord was just as long as the one on the PC. One feature I noticed and knew I would love was the trigger switch and trigger lock. It was exactly like the one on my Hitachi and I loved that. The speed dial (1-6) was a little hard to find at first as I was looking on top of the Flex and it is actually on the left hand side of the handle at the top. Makes it a little difficult to see but reduces the chance of moving it unintentionally.

Included in the box was a hex wrench for changing the backing plate and instruction manuals. I must say I was a little disappointed in the manuals as the instructions were encompassed into about 5-6 pages and very general. I brought the manuals in to work to read figuring I would have plenty of time to do it there and I finished them in about 10 minutes. If you are familiar with a PC or rotary this is really a non issue however I could see where it would be a problem for someone that mad the Flex their first buffer purchase.

Using it: Well to test it out I decided to use it on the 05 Volvo XC90 I just bought my wife. It had only minor swirling and some spider webbing as you can see from the pics:
I decided to use Menzerna 106ff and my green Lake Country CCS pad. The green pad is just a little bit coarser than the white polishing pad. Put my 106ff on the pad and spread it over a 2’x 2’ area with the machine off. I decided since I had not used it before to start at speed 3 and spread the polish then move up. I turned it on speed 3 and locked the trigger, did I say how much I love this feature.

Man this thing was strong even on speed 3. You can actually see the direct drive in action when you crank it up. You know how sometimes when you look down at the PC you think it’s spinning and then you think no it’s just jiggling, wait no now it’s spinning I’m sure, well wait a minute it’s sort of jiggling-spinning now. Well there is no doubt with the Flex. Well after spreading the polish I bumped it up to speed 5 and man it really started to feel like a rotary some. I have heard a few complaints about it walking like a rotary does. Well I really didn’t notice that but it could be because I have grown accustomed to it from my limited use of the rotary so it didn’t surprise me. Like I said though I really didn’t notice any walking at all. I worked the polish at speed 5 for maybe 2 minutes. I released the trigger and noticed that it does take longer than the PC to coast down. I wiped away the polish and the swirls were gone. Also gone are the days of having to work the polish 3-5 minutes to get out minor swirling. You can look at the after pictures and see what the Flex accomplished.

Before




Afters





I was able to polish the Volvo in about half the time that it would have taken me with the PC and the results were stunning. The swirl free finish that had an absolutely amazing shine to it had me standing there just staring at it. On a few of the horizontal panels I got a little brave and bumped the speed up to 6 just to see how it was. I have never been able to run my PC on 6 regardless of how bad the swirls were because the vibration was just too much. The Flex on speed 6 was an absolute monster but in a good way. I had no more vibration on speed 6 than I would get from the PC on speed 4. At speed 6 the Flex was like “Alrighty then let’s go fix some paint!” Also on speed 5, I really put some pressure on it and never got it to bog down one single ounce. This machine begs to be worked.

A number of times after working the polish before I would wipe it off I would feel the paint and it does get really warm. This machine is no poser, it’s really working. After polishing I decided to use some Chemical Guys Wet Mirror Finish with a gray Lake Country CCS pad. I always spread my glazes/sealants/waxes on speed 3 with the PC. Well I started at speed 3 with the WMF and it was just way to fast for it. I couldn’t get good even coverage at that speed. At this point I momentarily thought about going to the PC to put on the last steps, but man the Flex was working so well and felt so good working I wanted more time with it. My alternative was to turn it down to speed 2 and it did a fine job. I actually about ¼ of the way through turned it down to 1.5 and found that to work really well. I applied the JetSeal next with a red Lake Country CCS pad at speed 1.5 and next came the Megs #16 with a blue LC pad at speed 1.5.

The Flex got a taste of everything: polish, glaze, sealant, and paste wax and did a phenomenal job with all. Just a little trial and error with the speed settings but once I got those it was great. I could have stopped after the JetSeal but I was enjoying it so much I went on and did the Megs #16. Heck I was hating waiting the 15 minutes for the JetSeal to cure and then another 20 before I could put on the Megs.

Working the Flex on the side panels does take some getting used to because it is so much more powerful than the PC you really really need to keep two hands on it and that requires some adjustment for getting the lower panels. I just got me a folded up towel and got down on my knees and went to work (alright keep the jokes to yourself I know how that sounds). The only real difficulties I found with working with the Flex was around the bumper areas and on the back lift gate. Oh yeah and the roof as I’m used to being able to reach on out there with one hand and cover a lot of ground with the PC. I couldn’t do that when polishing but with the other steps at speed 1.5 I was able to one hand the Flex.

Final thoughts and analysis: The Flex is an absolute godsend for me. I wish I had been able to spend the time practicing with the rotary and really wish I could have had a mentor to really guide me because I think I would have really loved the Hitachi. But here in the real world I just didn’t have either so this was by far a great alternative. I did a paint correction on a black F150 with my PC and that was a JOB. I really wish I had been able to use the Flex as it would have taken less time and I would have enjoyed the job a lot more. After the F150 I really didn’t think I wanted to tackle anything like that again, but after my work with the Flex, “Hell line ‘em up!” If the PC just isn’t cutting it and you are thinking about stepping up to the UDM because it is a little more powerful I would say save some more money and skip the UDM and buy the Flex. You wouldn’t be disappointed if you did, I know I’m not!

 

dang...another tool I need to buy. First Zoran then you....hmm...Maybe I will fly south to get one.



Great review! What did you think of the paint? Last time I did a Volvo SUV it was hard with a rotary! The pics are great, I think the paint clarity has been improved greatly.

 

I was pleased with the paint and the workability. I must admit I know the girl that had this before I bought it and I thought it would have been swirled up a little more so it must be pretty good paint.

 

Zoran: If you read this, you can see what I am talking about in the pictures. High speed D/A's are where it is at. If you look at the bulb in the before pictures, then look at it in the afters you can see more of the bulb. Crisper sharper reflections are great!

Again! A+ write up. Thanks for this Wolfpacker!

 

VERY NICE!!!!

Need to add it to my collection!
How was the weight of the machine?

 

Almost identical to the PC but better balanced.

Thanks sneek and I made sure that I tried to take the after pics from the same angle as the befores just so everyone could see the sharpness in the paint after the polishing. And those pics were after polishing only.

 

Great review Wolf, thanks for taking the time to write it all up.

You paid $269 for it, right? And that comes with both the 6" and the 5" backing plate?

 

Yeah that's right I paid $269 and that must have included shipping too as I just looked at my credit card statement and that's all I was charged. And yes Powerhouse distributing guy told me he would ship me the 5" for free since there had been some issues with the velcro seperating from the 6" one. Powerhouse is out of Nebraska but they drop shipped from SC for me and I got it in 2 days.

 

That really isn't bad when looking at the price. It's $269, two backing plates and no tax or shipping. Bargain. Really is. Thinking about selling the PC and putting that money towards the Flex.

 

I don't think you would be disappointed at all. My PC is now regulated to shampoo detail and the backing plate was removed and aqua brush was put on!

 

thanks for doing the review, there is lots of great info there

 

No problem I've been wanting to do it ever since I used it on Sunday!

 

with the Canadian Dollar currently at 1.0988 I am really really tempted.....

 

Nice review. I like how you focused the camera on the paint and NOT the reflections. That makes a HUGE difference.

 

You make me want the Flex hahah. I'm still happy with my UDM, but I wish I can afford the Flex. Thanks for the review!

 

hhahahaha:rollinglaugh: I literally laughed out loud..you have owned everything.

Let's see
Metabo
Flex
Rigid
Metabo SXE
UDM
PC
Cyclo

You are like Nica...but with tools. Maybe you guys should hang out one day. Zoran brings the polishers Nica brings towels, PADS, polishes hahaha.

I am becoming poor! I think I will get a Flex and G110...but then I really need to stop!

 

How do you like it?? I was thinking about getting it because I could have had it for a really good price. The latest reviews are a mixed bag, so I didn't get one. Let me know what you think of yours. It seems light years a head of the V1

 

Thats a long list of testing right there. :worship:

Have you any thoughts on the Makita B06040? I like that it can be switched from a DA to a Rotary.

I will tell you that Sneek & ZoranC's arguement and research on short throw/high OPM polishers is what really convinced me as they made a lot of sense. I am truely happy and satisfied with my purchase. I know that it's not just new purchase euphoria either, because the first time I really did any paint correction with my PC after I bought it I was thinking man I need to get and learn a rotary. My thoughts after using the Flex for the first time was man I need to sell my rotarty.

 

Loving the info here!

So then is there a specific reason that you would need both the Flex and the Bosch if a rotary was allready owned? Im assuming that both the Flex and Bosch are being used to replace the Porter Cable and UDM by being more powerfull and higher user comfort. Im thinking I dont understand the ability of the tools (or definition of forced rotary and its purpose)


If Im taking this thread wayyy off cource let me know and I will start a new one.
