Re: Whats Marring?

Re: Whats Marring?

Marring is just light really really light scratches or like "smears" that are etched into the paint, if I'm not mistaken.

Re: Whats Marring?

Marring is caused by lots of things. A cheap MF towel, some dirt in a wash mitt, some clay baring (this a real word?), using a compound or heavy polish will remove the deeper swirls and scratches but at the same time mar the paint, that is why you follow up with another lighter polish or 2.

Re: Whats Marring?

Something like scuffs in the CC. You can even marr the paint if you don't use enough lube while claying.

Re: Whats Marring?

Essentially marring is hazing and/or swirling on the clearcoat. Marring is usually caused by improper use of a DA polisher or rotary buffer and/or using too much pressure or too aggressive of a product. It can also be caused by the items that Sal329 mentioned. Example:

The matter gets even more complicated if the clearcoat gets burned, as illustrated here:

So, in a nutshell, that's pretty much what marring is. Hope this answers your question!

So, Mario, are you saying that M105 "kinda" burns the cc?

Is this the official Meguiars position? "IF" M105 induces some level of marring and as you say marring is "kinda burning the cc", then it is safe to say the M105 "kinda burns the cc".

I don't think that is correct, but I'll leave it to the Megs pros to correct it.

Re: Whats Marring?

Anything can marr the clear coat depending on usage and application.

Marring is the result of getting rid of swirls, scratches or anything else. It's a desirable effect (in the sense of it being the outcome) to remove defects (or rather VS having defects) but it's not a desirable after-affect to leave on your vehicle. You want a mirror finish not a marr'd finish..


..I think that was a horrible explanation but it's too early here lol

Re: Whats Marring?

I don't think marring should be described as burning whatsoever, especially since it can be caused with no heat whatsoever... I would best describe it, like someone mentioned above, as smears in the paint... smears can look like swirls, scratches, hazing, etc. but it's nothing deep and can be easily fixed by polishing with a light polish/pad combo... if something like a quick step of M80/8006 on a G110 doesn't remove it I wouldn't consider it marring... just my definition of course...

Oh and I think the easiest way to marr the paint is with something like a Meg's red pad... use some pressure and clay in one spots for a bit and you'll see something that looks like haze/oxidation as well as a few swirl marks... it'll clean right up but that's marring imo

Re: Whats Marring?

I agree with the above poster. My definition of marring is that it's lightest type of defect. Burning is the severest. They seem very extreme.

Mind you, the process of creating a mar can eventually burn, but then it's no longer a mar, it's a burn.

Well, one of the reasons why MOL is so valuable is that it is a place to get ACCURATE information.

I don't think it helps anyone to be providing informatin to others unless you are 100% sure it is accurate. Now, I'm NO expert on marring or anything else detailing related so I offer my opinions very rarely.

There are others here that I think have LOADS of info to pass on to the rest of us, so I think it is important the info stays accurate.

(BTW - not suggesting your post is not accurate - I'm just not convinced about the earlier post about marring being "kinda like burning the cc".

Yea I understand... at the same time though people will have their own interpretations of certain detailing terms and I doubt it'll ever be 'perfect' so to speak... marring in it's purest definition means to ruin a surface in a way, and basically it's a defect, a blemish, a flaw in something... based on this we can easily call swirl marks, buffer trails, and everything else marring... from my experience though, marring took on the meaning of lighter defects that one is able to polish out fairly easily, but defects that should no doubt be avoided... that is why my best definition of marring would be the surface defects claying with a more aggressive bar leaves behind... looks something like a bird poop etching but it's not nearly as bad and is corrected easily.

EDIT: I too am looking forward to seeing how some of the more experienced detailers on the site define the term

Thanks in advance,

Did you read the hundreds, if not thousands of threads where a guy used a PC with M105 and there was no marring? Share the link so we can all read it because besides M105 another HUGE factor is the type of pad that is used, the speed setting and the technique. Don't let one person's mistake keep you from using a super product.

In the context of machine buffing automotive paints using a Dual Action Polisher, marring is a term used to describe the scratch pattern instilled into the paint by a combination the type of pad used, (for example a cutting pad), type of abrasive product used, the oscillating action in and of itself, and technique, which can include downward pressure, buffing time, speed setting, pad angle, etc.

Besides all of that, paints are different. There are about a dozen automotive paint manufactures in the world and each one makes their own types of paints and some paints buff really well and some paints buff horrible.

Also the hardness and softness of a paint will be a huge factor as to whether any specific paint will be prone to marring or not.

For all of the above reasons, this is why on this forum we started the idea of teaching people to do a TEST SPOT and dial-in their process and prove it works to themselves to a small area before going over the entire car.

This is also why we've been about the only company that doesn't recommend using a cutting pad on a DA Polisher and that's because all too often the aggressive nature of most foam cutting pads will induce marring or scratches into the paint.

Here's thread from our Hot Topics forum from 3 years ago that shows marring caused by a popular orange foam cutting pad used on a Porter Cable Dual Action Polisher.

Cutting Pads with the PC - Is this a good idea?

Once in a while people come to MOL asking questions about using foam cutting pads on the dual action polisher, (G100/PC). Here at Meguiar's our current policy is to not recommend, nor sell people cutting pads to use to apply products with the dual action polisher because while they may remove scratches, they tend to scour and haze the paint and most people don't have the skill or expertise to recover from this when it happens.


Below is a picture of the hood on GTBrad's black Mustang.

• - In the upper left hand corner you can see swirls in the paint that were there when Brad bought the car.
  - In the upper right hand side is how the hood looked after he tried using another company's cutting pad on the dual action polisher. Note how scoured the paint looks.
  - In the bottom half of the hood, we removed both the swirls and the scouring using Meguiar's products and only our W-8006 polishing pad and our W-9006 finishing pad.

The point is, using the correct technique, you don't have to resort to a foam cutting pad and risk scouring your car's paint to remove below surface defects and restore a show car shine!


The hazy look in the RIGHT HAND CORNER is Marring, or Micro-Marring.

Please also not how the marring in the paint the above picture was taken from was removed by simply switching to a less aggressive foam pad.

Light damage

Correct. Marring, or Micro-Marring could be considered light damage.

not burring through the cc but "kinda" burning the cc

This is incorrect. Marring and burning through the clear coat are two completely different things.
