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.

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...

Since it's dual action.
Mike's exact words in this video: YouTube
"Virtually impossible to damage your
clear coat with this polisher."
IMO:
Below (highlighted in Red) is the difference...
the game-changer, as it were.

The total paint build is thinner
on the corners/edges.

It's just like it turned color.
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.

compromised area; prep; and respray.

Re: Very unique damage with Porter Cable Polisher and Meguiars M105
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?
