I did some paint correction this weekend on one panel with a PC and m105 (orange) and m205 (white) pads. They are Chemical Guys hex pads if that makes a difference.

There is improvement that the swirls are gone, but some of the deeper scratches are still visible, but what I can't seem to get rid of is the marring.

See the link, in the middle, the two white lines. Any tips on how to get rid of the marring. Should I use a different compound or pad? Much appreciated.
 
It's hard to tell from the images, but I wouldn't call that marring.... :-\
Are you sure those are scratches? Was it there before you started "correcting"?
I'm sorry but it looks almost like a burn in the clear coat.

M105 is SMAT technology with a cut level of 12 on a scale of 0-10.
If you couldn't clear it up with Orange Hex & 105, there may be something more sinister going on.

If they really are scratches and not clear-coat burn, perhaps some 5000 grit trizact (to start) followed by 105/205.
But again, I'm just taking a shot in the dark because I can't tell from your photo's.
If they really are "scratches", and you were a customer and I already went over the car with 105/205, IMO, I'd stop there...

My suggestion would be to get a second opinion... Perhaps a reputable body shop.

Did you mean to say holograms on left side of the picture there the hose reflection is?

Yea you can see "wavy" hazy lines if you look at different angles. I think its the clear coat on the paint, I have heard other bmw users with different colors, especially "Jet Black" paint and they can't use a DA polisher on the clear coat.

^^ Not sure as my jet black is Audi's Brilliant Black and the best fine polish I've used and like is Menzerma SF4500. No marks or anything. Just pure black goodness.

Do you see those marks anywhere else on the car?

Yea there are, mainly at the doors. You can only see them when you are looking at it from eye level. I guess I only really noticed it when I was doing that one door and was sitting on the floor.
 
I have used a 3401 and Rupes on an E92 in Jet Black, no issues.
 
Looks like hologram marks to me. Hit the area again with m105 and orange pad, then with m205 and white pad.

Could you explain more on why BMW owners with Jet black paint can't use a DA on their clear coat?

Lots of threads on this forum and others about the soft clear coat of the Jet Black. DA works great for the Black Sapphire Metallic paint color. I have Estoril Blue but wasn't sure if it was the same "softness"

While jet black paint found on BMW's may be on the softer side of the spectrum, there is no issue of polishing the paint with a DA unless the owner of said vehicles are using inferior products/technique.

Let me rephrase Mike's statement a bit. Understanding the paint surface, the defects involved, then applying the proper technique and product will yield results.

Example: Recent video by a well known detailer was working on a Porsche with soft paint. Everything he did caused marring (DA haze). Understanding the product he was using, M205 as SMAT (non diminishing abrasives) he came up with a technique on the fly by which using a white polishing pad, added a pea sized drop of M205 then rinsed his polishing pad in a utility sink.

Using a spray bottle of distilled water, he sprayed the panel of the vehicle and the pad, and using a low speed on either Rupes or Flex, was able to polish to a very high gloss without marring. Could he have achieved these results with a diminishing abrasive such as Menz 4500 or Pinnacle Advance Finishing Polish, maybe... maybe not.

It came down to understanding the characteristics of the product, pad, machine and coming up with a technique that worked.

Now, back to your photo's. It would be helpful if you edited the photo with a circle of the area that contains the information you want transmitted. Judging by the photo above, I'm assuming that vertical cloudy area mid panel is the information we need to analyze, or are you indicating the scratches along the rocker panel? Circles and arrows would help.

If you're referring to the vertical lines/cloudy area mid-panel, I do not see that as DA marring. I questioned if it were there before you started working. How much have you worked that area? If M105 & 205 are not taking it out, you could be making it worse by removing clear coat.


1.) When doing your section passes, are you doing them in a cross hatch pattern with 4-6 passes per section?

2.) Have you tried a less aggressive pad or product or lower speed on the PC?

3.) If you spray some water on the area does the defects go away?
