PC 7336SP - Very Unimpressed

**Malu59RT** · 12-13-2006, 01:12 PM

I spent 6 days last week and over 20 hours detailing my M3 to get out swirls, and I was very disappointed with the buffer. 2 hours into using it, the head made a metallic noise over the '5' setting, and it finally pooped out on me with 3 panels left to finish. I had used a rotary before, and the detailing forum on the site I went to highly recommended the PC. I admit, it's good for a beginner, but wanting to do 5-6 cars a week is totally unfeasible with a PC. Also, a decent amount of swirls came out, but there were several extremely fine scratches that were left in the paint that should have come out also. It took way too much time to do the car, and that's one of my biggest complaints (that and the buffer failing mid-job). I plan on getting rid of this PC and buying a rotary (the Dewalt 849) is what I am looking into. However, I am glad that I found Autogeek, as their customer service and the forum/store layout is excellent.

BTW, I highly recommend the 3M Foam Polish for Dark cars. I used the Detailers Pride swirl remover, and 2-3 other products, and was at my wits end until I bought the 3M product. It appears that Saleen281 and I have had similar experiences.

Hi Jason,

As you pointed out the PC is really an enthusiasts' tool. It's not really an appropriate tool for professional use as it takes too long to break down a polish. Plus, it doesn't generate a lot of heat as a rotary does. So often two polishing steps with a PC are required instead of one with a rotary to get the same result. Technique is also quite different with a PC compared to a rotary. The PC needs to be moved REALLY slowly across the paint to achieve maximum results. As you already know the PC is a safer, easier to use machine. However, the rotary is much faster but is dangerous in the wrong hands.

If you're already experienced with a rotary then there was not really any reason for you to use a PC. I didn't see a thread from you on S2KI.com on this subject, but had I seen it I would have told you not to bother with a PC.

I'm surprised your PC "pooped out" on you during its first use. I've had mine for a couple years now and it's never gone out on me. I also know Scottwax on Autopia used the same PC professionally for several years before it pooped out. Did you buy one that was refurbished?

MikeyC, you will remember my screen name on the Lowe's post .I think more than anything, I was just upset that it died in the middle of a job. On top of that, there was very bad vibration when I used it. You will notice that I picked up one of the "clearance" ones for $89.99 brand new, so it's pretty bad a brand new one messed up that fast. In fact, probably the only thing I enjoyed using it for was applying wax. I usually apply wax by hand.

I've been detailing cars since I was 12, but it's not a full time job for me. I do my friends and family members cars all the time for free, but to do those cars now, I will need to pick up a rotary. On the bright side, the Edge pad kit was a great product, but my adapter seemed a little hard to push in to release the pads. I will try to post up pics when I finish the interior of the car.

Yeah the PC is know to vibrate a lot. I'm glad to hear you like the Edge pad system. The machine vibrates even more when you use velcro pads if you can believe it. One tip though . . . if you put one hand on the head of the machine instead of using the side handle the machine is easier to control and makes less noise. The black plastic cap on the head of the machine is not attached very well for some reason.

I would definitely try to bring the machine back to where you bought it. There's no reason it should poop out so quickly. Then get yourself a rotary. You'll be much happier since you already know how to use one. If I was experienced with a rotary I would not be using a PC.

Aside from the DeWalt you may also want to consider the Hitachi and the Makita. I understand those machines are lighter than the DeWalt which can result in less fatigue when detailing.

For the novice and weekend detailer a Cyclo or PC is still the better investment. Safety is the major concern. Once you realize and obtain the learning curve of the PC, you will be amazed at what it can do. I will agree that a rotary has a place in detailing, but its on a professional level or someone graduating from their PC to the next level.

I guess we will have to agree to disagree. I am a weekend detailer, but in anything, I guess I use more common sense than others when I use equipment, especially when people repeatedly warn you not to keep it in one spot, don't turn the speed up too much, etc. I don't think the time that I spent with the PC would even out to a better investment. I sat there the entire time wondering if everyone else really was taking this much time to remove their swirls. In the past, my only problem was not having the right type of pad for the job.

Also, I apologize for the site link, but I was curious on how it is a competitor site? There is not a classified section or store, for detailing supplies. In fact, that site is where I got a link to Autogeek, and I would never have known about it if it wasn't for them.

Sounds like a technique problem to me. To go straight out and be unimpressed with a tool because you dont know how to use it to its full extent is not right. It is very rare for a new PC to just dump on you like that. You should learn how to use one before going straight to a rotary however.

Also, you dont one step polish with a pc. To use a more abrasive polish first, then you almost always have to clean up with a finishing polish. The pc is not a one step tool.

And as far as it not being feesible to do 5-6 cars a week with the PC, take a look at Justin's work. He has made some truelly amazing transformations happen with the PC. Half the ability of using a DA OR rotary polisher is the correct knowlege of pad and product choice.

Here is a example of what a PC can do in the hands of a 17 year old whos read up on their information for a long tiem before making an investment such as the PC:

Patient: 1995 camry, rental car purchased by my grandmother in 1996, and given to me in 2005.

This was the car, ALL OVER

I have the same model and it works great, you should bring it back because I think they have like a 30 day return policy and that is a defect in the product if it already broke. A PC is very capable, but if you already know the rotary, you shouldn't really step down to a PC for polishing as others have said above. I know some who use a rotary for polishing and a PC for glazes, waxes, etc. Good luck and let us know how it works out.

I never said the PC didn't remove any swirls, but the time that it took was not something that I need to deal with. If you have read above, I have rotary experience, in fact, that is what I learned to machine polish with, but it was borrowed from a friend and he wanted it back, which is why I was in the market for a polisher. At the rate that I was moving on the car (making sure the polish actually worked in and broke down) and with having about 2 hrs a night to work on the car, I don't see how I could do 5-6 cars in a week with a PC. I did my research on the PC before I bought it, and people were getting great results, but I guess I never knew that it would not provide better results than a rotary. No one was posting "look, no swirls, but it would be better with a rotary" It was my mistake and I will correct it by getting the correct tool for the job.

BTW, partial list of cars I've done with the rotary before:
02 Z06
00 Prelude w/$2k custom paintjob
02 S2000 w/$2k custom paintjob
03 MB S500
02 MB E430
04 GSXR-1000 w/$2500 custom paintjob
and I will redo my 05 M3 with the new one, and do my 06 GS430 with the rotary friends S4, Supra, and S2000

I didnt say you had no experience with a rotary, if I over reacted, forgive me. Its crazy how many people go nuts because the PC didnt do everything they had hoped or overhoped.

If you have already mastered the rotary, just return the pc for another and use it for soft paints. On hard paints however, that is when the roatary is needed.

Where did you first learn how to use the rotary? Its just so unusual to go straight into one! Also if you are going to do more high end cars, invest in a paint guage. There are a few people around here that abuse their cars, get them buffed out and repeat. The result is angry owners with no clearcote.

This can help you avoid clear failure issues with the rotary! Its taken me so long to get one just because Ive been saving for the dam paint guage as well.
