  • DISO - how to correct?

    Hello Everyone!
    Been reading up voraciously on the forums in preparation for my first machine detail job! I picked up a new SUV about 2 weeks ago (Hyundai in Beckett's Black i.e. black pearl). Long story short, car looked good during delivery, but once it went through the rain a day later, all the swirling "mysteriously" appeared! Looked like someone had buffed the car with a dirty pad! This is what I was looking at:





    The dealer requested to have their in house detailer try to correct the issue - apparently he did a 2 stage polish - didn't look noticeably better. I then took it to a highly reviewed detailer, that significantly improved the appearance of the swirls under the over head florescent lights, but unfortunately, once in the sun, was still quite evident. Apparently he used automagic GS-1 and followed by new car glaze. Here's how it looks in the same light conditions as the previous pictures, with 2 layers of collinite 845:



    I can't stand the fact that my new car's paint looks worse than my 5 year old Mazda (granted, the mazda is gun metal, not black), in the sun anyway. I am planning on trying to do this myself now with the Ultimate Compound and Ultimate polish combo, and I have a few questions:

    1. Should I be worried that 2 other detailers have gone before me, albeit with relatively non-agressive (and evidently not aggressive enough) polishes, in terms of thinning out my clear coat?

    2. Is UC too aggressive given these swirls look relatively light?

    3. I was thinking of using something equivalent to a UC w LC orange pad, then UP with a white polishing pad. I might even try UC w the white pad first to see what results I get. I know it's really hard to judge based on pictures, but any recommendations/comments on this plan of action?

    Oh, this will be done with a PC 7424 (non XP I believe).

    Appreciate any inputs! Thanks!

    First off, welcome to MOL!!

    Second, congrats on the new ride!!

    Third, don't let it bother you at all that the car has already been detailed and that your process could thin out the clear to a worrying degree. If those who tried and failed previously had actually removed any clear, these swirls would be gone. To your point, these look pretty minor in the grand scheme of things, but of course being on black paint they're just sort of jumping out at you. But in the overall universe of potential paint defects, these are pretty mild.

    So that brings us to your potential process to remove these. And we say "potential" because, as you well know, you've got options here. The really big variable that we can not directly address, and the one that will dictate which exact process you need to fix this issue, is the paint itself. We aren't worried in the least about using Ultimate Compound; remember, the aggressiveness of any compound can be altered by your pad selection, tool speed, pressure, etc. We'd start with Ultimate Compound on a polishing pad and do a test spot with that, evaluating the progress and adjusting from there. If a singe section pass (up/down - side/side - repeat both directions at speed 5 on the tool with moderate pressure and slow arm movements over a 2' x 2' area) removes the majority of the defects, then an additional pass is likely all that's needed with that same liquid/pad combo. If, on the other hand, that process only removes a small percentage of defects then step up to a cutting pad. Keep in mind that you may need a second step if the paint is very touch sensitive and shows a bit of haze after compounding. Some paints exhibit this, others are fine going straight to wax after compound. That's something for you to discover and adjust your technique accordingly. That secondary step is likely something like Ultimate Polish on a foam polishing or finishing pad, depending on which pad you needed with UC to correct.

    A textbook scenario would look something like this:

    Ultimate Compound/cutting pad
    Ultimate Polish/polishing pad
    Ultimate Wax/finishing pad

    But the real world sometimes throws a curve ball and you find that UC on a polishing pad is all that's needed. In that case, you may do UP on a fresh polishing pad, or you could go with a finishing pad. Again, that decision is ultimately dictated by the paint and your goals.

      Wow, thanks for your comprehensive response Michael! Appreciate having the experts review my plan of action and add some refinements! Will have to squeeze this in now to the list of 1001 things I have to do this weekend. Thanks again!

        Darn, previous post disappeared - shortened version is: I tried out UC and PC 7424 on my inlaws 3 year old Acura which has goes through harsh canadian winters where their put dirt on the road, dealer washed, and kept clean with a single bucket/single mitt wash system. In short, it was so covered with scratches the car basically has a bit of a matte appearance!

        Before:




        I ended up doing one section pass with UC and a polishing pad. Got rid of around 70% of the scratches - you can make out the dark line in the middle where my first section ends:


        I then went to the UC on a cutting pad for one section pass, UC on a polish pad for another section pass, and UC on cutting/polish pad as required for the problem areas for a few extra passes. Results:


        I'm pretty impressed with how easy it was to use the PC 7424 and UC combination, and very happy with the results considering it was my first machine polish!

        Only downside is I still have to do my car, but I also have to do the inlaw's car now too!!

          Once you get those Swirls out, just use Ult Polish 2-3 times a year before you wax...

            Alright - update on the penultimate final results with my car! Armed with a PC7424 (yes, w/o the XP), 6" Meg cutting, polish, and finishing pads, Meg Ultimate Compound, and about 7 hours spread over a couple of days, I went to town on the car. Here are the before and after pics - the after is post compounding, prior to polishing (not convinced I want to do that yet, as the paint is just about where I want it and there's many other projects waiting for me...), and prior to LSP which is going to be collinite 845.

            After
            (Fingerprint was to try to get the camera to focus)





            Will post some pics once I polish(maybe) and wax the car.

We can go out for a drive without her makeup and she looks fine. If I want to take the black one out, it is three or four hours in the "bathroom" to get ready.

                I agree it looks much better.

                I posted the same on AGO. But how do you know the clear is thing? Did you use a pint gauge to measure?

                If it were me I would still polish just to refine the finish and add that gloss. Then seal. Try some polish on a finishing pad.
