    Very unique damage with Porter Cable Polisher and Meguiars M105

    First off. Hopefully you can see the picture. It was in the dark with flash.

    Not sure what this is or what to think about it.

    My buddy was using my Porter Cable XP Polisher with Lake Country Orange pad and Meguiars M105. He was getting some deeper scratches out of his truck. All was going well.

    Then he hit the corner. You can see it in the picture.

    There is a part that is a little bigger than a dime that turned white. The paint did not chip! If you rub your finger over this it feels just as smooth as any other part of the surface. There is no indentation or anything like that. All totally smooth.

    It's just like it turned color.

    So, what is this?

    And how do we fix it?


    Thanks!!!

    Looks to me like he burned through the clearcoat

    But if he burned through the clear, wouldn't you still see black? not white.

    He burned through the paint. Paint doesn't just change colors.

    If he burned through the clear and the paint, why can you not feel it?

    If you run your finger over this, you cannot feel it. I mean it feels just like a freshly waxed car. No dips or anything.

    Secondly, I thought you cannot damage your car with the Porter Cable 7424XP? Since it's dual action.

    Mike's exact words in this video:
    YouTube
    "Virtually impossible to damage your clear coat with this polisher."

    Which makes me wonder if it is clear coat damage?

    Tough to tell from you that pic. I will say for an area that just got gone over with 105 that it looks pretty bad tho..... makes me wonder.

    Looks like burn through to me as well. My buddies Lexus had a similar spot that was smooth in nature that somebody did for him. And not to be silly but "virtually impossible" is not the same as "impossible"

    Did you measure the paint by chance. Folks have burnt through clear with the greatest of intentions using a DA polisher. Good luck...

    IMO:
    Below (highlighted in Red) is the difference...
    the game-changer, as it were.

    All was going well.

    Then he hit the corner.
    The total paint build is thinner
    on the corners/edges.

    So, what is this?
    •Even though a “burn-through” can’t physically
    be detected at this particular point in time
    (Alas: it will become more, and more physically
    detectable in short order)...
    -The paint-system was (over)heated to the
    point that it’s binders, resins, etc. have been
    compromised, and is no longer bonded to the
    underlying panel/substrate.

    The “best practice” fix is: remove the
    compromised area; prep; and respray.

    Could it be an old repair that had a thin paint on it. The shape looks like a small dent that was filled and painted. How did the pad looked after going over it? Was it any signs on black paint on it?
