"The Porter Cable 7424 Dual-Action Polisher is the perfect buffing, polishing and detailing machine for the car care perfectionist. This is the detailing machine that made hand polishing obsolete! The random-orbit, polishing action of the 7424 will give you swirl-free results without burning your paint or removing excessive amounts of clearcoat. The Porter Cable 7424 Dual-Action Polisher is the best machine polisher on the market today!"

I was reading about this buffer and I came across that saying " without burning your paint or removing excessive amounts of clear coat..."

I was just curous to say that running any buffer at a real low rpm like 1500 where most people run it I believe wont burn up any clear coat correct?
 
Well the PC 7424 is a dual action machine so there are no RPMs. The RPMs are with the Rotary buffer. The PC 7424 is difficult to burn through the paint but it could happen with a matter of abrasive products, pads, thin or poor paint and so on.

As for the 1500 RPMs, the same deal with the 7424 but just a lot easier. Since the rotary only spins, the same patch of paint gets touched by the pad more which generates heat which burns the paint. 1500RPM can burn the paint with a Rotary, which I would only buy one if you are trained correctly or know and understand how to use the PC 7424. Hope this helped.
 
It is pretty hard to mess the paint up or burn it with the PC unless you are trying to or you use the wrong products even on speed 6.

Ahh I keep getting so many mixed responses I heard you cant burn paint at all with a porter cable buffer...I thought you could just burn with rotary...

So I shouldnt get a porter cable if it will be my first time like removing swirls etc?

Also all the pads confuse me too

You really have to try to hurt the paint to screw things up. You do not want to apply pressure let the weight of the machine and the pad and product do the work. Get the PC we were all first timers at some point. I would suggest you start with the Lake County White Polishing pad and some SSR1 probably the least aggressive stuff to begin with and once you begin getting comfortable or you see this product is not working or doing what you want move up. Also if you post pictures of what you are trying to fix many here will be able to tell you what to use. Do not be afraid of the PC it is your freind.
Here are a few links that may help you learn a little more.

Basically I just need the pc to remove light swirls and sometimes even heavy swirls on some cars...such as my moms old jeep .....and I mean I get the process such as wash, then claybar, then wash again then you can go to removing swirls and then polishing and getting it how you want it and then sealing it and stuff just all the pads confuse me....

Here is a chart that you can refer to that will make it easier for you to decide what you need for the vehicles that you will be detailing. The chart is self explanitory. All you have to do is evaluate the paint surface then choose the products that you will need to complete the detail.

There is another chart that fellow DC member, Jaybs95, made up that is very good. I refer to both of these charts often. They are a very good tool in explaining what is needed to do the job.

Good Luck!!
 
The charts are great..

However Im going to be using the new mothers products the power line.

I bought claybar, and then I bought the 2 step power process the Power Polish and Power Wax, and then I guess I need some sort of sealer which I could use, but what type of pads should I use for the 2 step power process....just regular polishing pads unless there are rough swirls?

Sure didnt but oh well....

Does anyone know what pads I should use for those products?
 
I would start out with your white pad and see if it is cleaning up your swirls if it's not then go up to the orange pad. Just like everyone says start out with the least agressive pad and product first . Let us know how it goes for you :yes: some of us haven't used our pc's yet :yes:
 
I would say start with the polishing pad but I bet you'll need to step up to a cutting pad with the Power Polish. But if you don't have too many swirls you may be okay. I haven't used the Power Wax- but I wouldn't top that with a sealant so you really don't need one unless you want to go from the polish to your new sealant. I used the FX Synwax by Mothers and had a little better durability with that than Meguiars NxT. One more thing, the Power Polish can be agressive with an agressive pad or it can be gentle with a polishing or finishing pad. A product that is quite useful, IMO.

I would get ahold of Matt and see if the disount can still be applied. 10% is a lot when you consider the amount of the order. It cannot hurt to ask. :yes:

VERY TRUE!! :yes:
 
Appreciate the responses, my swirls are very light however you can see them in some areas in the light so I might have to use the orange pad, however I will start w/ a polishing pad first....

Also should I run it at 1500 or what speed would be the best...
 
Your getting the Dual Action PC confused with the rotary again. The PC has 6 speeds, no RPMs. You will probably be best off with speeds 5 & 6 if needed. I'm not positive but the Power Polish may have some fillers in it, I never got a straight answer with that. But ya start off with the least abrasive, work the speed up and if that doesn't work, resort to the cutting pad.
 
Alrighty, I didnt think people really ran there pc's at 5 and 6 I always thought like 3 and 4 haha I guess im still learning :)
 
Well thats where I found it to be most productive. I'm sure you'll pick up on it once you start working with it and gaining experience.
 
Ill probably run it around 4 I guess to start off with and then speed up depending on how the results are turning out, I guess its all in learning.

Do the majority of people run it at 5 or 6?
